This paper compares alignment methods with ROC curves on CATH database. ``Seven protein structure comparison methods and two sequence comparison programs were evaluated on their ability to detect either protein homologs or domains with the same topology (fold) as defined by the CATH structure database. The structure alignment programs Dali, Structal, Combinatorial Extension (CE), VAST, and Matras were tested along with SGM and PRIDE, which calculate a structural distance between two domains without aligning them. We also tested two sequence alignment programs, SSEARCH and PSI-BLAST. Depending upon the level of selectivity and error model, structure alignment programs can detect roughly twice as many homologous domains in CATH as sequence alignment programs. ... These results help quantify the statistical distinction between analogous and homologous structures, and provide a benchmark for structure comparison statistics.''

"Approximate protein structural alignment in polynomial time,"
PNAS, 101, 33, 2004, pp. 12201-12206.
Here, we study the structural alignment problem as a family of optimization problems and develop an approximate polynomial-time algorithm to solve them. We argue that such approximate solutions are, in fact, of greater interest than exact ones because of the noisy nature of experimentally determined protein coordinates.

This is the main reference for Feature. ``Sites are microenvironments within a biomolecular structure, distinguished by their structural or functional role. A site can be defined by a three-dimensional location and a local neighborhood around this location in which the structure or function exists. We have developed a computer system to facilitate structural analysis (both qualitative and quantitative) of biomolecular sites. Our system automatically examines the spatial distributions of biophysical and biochemical properties, and reports those regions within a site where the distribution of these properties differs significantly from control nonsites. The properties range from simple atom-based characteristics such as charge to polypeptide-based characteristics such as type of secondary structure. Our analysis of sites uses non-sites as controls, providing a baseline for the quantitative assessment of the significance of the features that are uncovered. In this paper, we use radial distributions of properties to study three well-known sites (the binding sites for calcium, the milieu of disulfide bridges, and the serine protease active site). We demonstrate that the system automatically finds many of the previously described features of these sites and augments these features with some new details. In some cases, we cannot confirm the statistical significance of previously reported features. Our results demonstrate that analysis of protein structure is sensitive to assumptions about background distributions, and that these distributions should be considered explicitly during structural analyses.''

``A protein site is a region of a three-dimensional protein structure with a distinguishing functional or structural role. Certain sites recur in different protein structures (for example catalytic sites, calcium binding sites, and some types of turns), but maintain critical shared features. To facilitate the analysis of such protein sites, we have developed a computer system for analyzing the spatial distributions of biochemical properties around a site. The system takes a set of similar sites and a set of control nonsites, and finds differences between them. Specifically, it compares distributions of the properties surrounding the sites with those surrounding the nonsites, and reports statistically significant differences. In this paper, we use our method to analyze the features in the active site of the serine protease enzymes. We compare the use of radial distributions (shells) with 3-D grids (blocks) in the analysis of the active site. We demonstrate three different strategies for focusing attention on significant findings, based on properties of interest, spatial volumes of interest, and on the level of statistical significance. Finally, we show that the program automatically identifies conserved sequential, secondary structural and biophysical features of the serine protease active site, using noncatalytic histidine residues as a control environment.''

``BACKGROUND: Serine protease activity is critical for many biological processes and has arisen independently in a few different protein families. It is not clear, though, the degree to which these protease families share common biochemical and biophysical properties. We have used a computer program to study the properties that are shared by four serine protease active sites with no overall structural or sequence homology. The program systematically compares the region around the catalytic histidines from the four proteins with a set of noncatalytic histidines, used as controls. It reports the three-dimensional locations and level of statistical significance for those properties that distinguish the catalytic histidines from the noncatalytic ones. The method of analysis is general and can be applied easily to other active sites of interest. RESULTS: As expected, some of the reported properties correspond to previously known features of the serine protease active site, including the catalytic triad and the oxyanion hole. Novel properties are also found, including the spatial distribution of charged, polar, and hydrophobic groups arranged to stabilize the catalytic residues, and a relative abundance of some residues (Val, Tyr, Leu, and Gly) around the active site. CONCLUSIONS: Our findings show that in addition to some properties common to all the proteases examined, there are a set of preferred, but not required, properties that can be reliably observed only by aligning the sites and comparing them with carefully selected statistical controls.''

WebFEATURE is the public interface to the scanning algorithm of the FEATURE package, a supervised learning algorithm for creating and identifying 3D, physicochemical motifs in molecular structures. Given an input structure or Protein Data Bank identifier (PDB ID), and a statistical model of a functional site, WebFEATURE will return rank-scored ``hits'' in 3D space that identify regions in the structure where similar distributions of physicochemical properties occur relative to the site model. Users can visualize and interactively manipulate scored hits and the query structure in web browsers that support the Chime plug-in. Alternatively, results can be downloaded and visualized through other freely available molecular modeling tools, like RasMol, PyMOL and Chimera. A major application of WebFEATURE is in rapid annotation of function to structures in the context of structural genomics.''

``We have developed an extension to the molecular visualization program Chimera that integrates Feature's statistical models and site predictions with 3-dimensional structures viewed in Chimera. We call this extension ViewFeature, and it is designed to help users understand the structural Features that define a site of interest. We applied ViewFeature in an analysis of the enolase superfamily; a functionally distinct class of proteins that share a common fold, the alpha/beta barrel, in order to gain a more complete understanding of the conserved physical properties of this superfamily. In particular, we wanted to define the structural determinants that distinguish the enolase superfamily active site scaffold from other alpha/beta barrel superfamilies and particularly from other metal-binding alpha/beta barrel proteins. Through the use of ViewFeature, we have found that the C-terminal domain of the enolase superfamily does not differ at the scaffold level from metal-binding alpha/beta barrels. We are, however, able to differentiate between the metal-binding sites of alpha/beta barrels and those of other metal-binding proteins. We describe the overall architectural Features of enolases in a radius of 10 Angstroms around the active site.''

"Recognizing protein binding sites using statistical descriptions of their 3D environments,"

This is the main reference for matching of binding sites with Feature. ``We have developed a new method for recognizing sites in three-dimensional protein structures. Our method is based on our previously reported algorithm for creating descriptions of protein microenvironments using physical and chemical properties at multiple levels of detail (including features at the atomic, chemical group, residue, and secondary structural levels). The recognition method takes three inputs: a set of sites that share some structural or functional role, a set of control nonsites that lack this role, and a single query site. The values of properties for the query site are compared to the distributions of values for both sites and nonsites to determine the group to which it is most similar. A log-odds scoring function, based on Bayes' Rule, computes a score that indicates the likelihood that the query region is a site of interest. In this paper, we apply the method to the task of identifying calcium binding sites in proteins. Cross-validation analysis shows that this recognition approach has high sensitivity and specificity. We also describe the results of scanning four calcium binding proteins (with the calcium removed) using a three-dimensional grid of probe points at 2 A spacing. The probe points that have high scores cluster around the true calcium binding sites, with the highest scoring points at or near the binding sites. The method fails in only one case where a calcium binding site is created by four proteins in the crystal lattice, and is thus not recognizable within the crystallographic asymmetric unit. Our results show that property-based descriptions can be used for recognizing protein sites in unannotated structures.''

We make the results of our analysis available graphically over the world wide web. To illustrate the validity and utility of our analysis, we used the amino acid comparative profiles to construct a substitution matrix, the WAC matrix, based on a simple summary of the computed environmental differences. We compared our matrix to BLOSUM62 and PAM250 in BLAST searches with query sequences selected from 39 protein families found in the PROSITE database. Although BLOSUM62 was the most sensitive matrix overall, our matrix was more sensitive for some families, and exhibited overall performance similar to PAM250. Our results suggest that the radial distribution of biochemical and biophysical features is useful for comparing amino acid environments, and that similarity matrices based on the geometric distribution of features around amino acids may produce improved search sensitivity.''

This paper contains results of an experiment for comparison of a few binding site surfaces to a large database (almost all binding site surfaces in the PDB) using the method described in [Kinoshita03]. Since partial surfaces are matched, a similarity scoring method is introduced that considers both a normalized score for the match of the geometry and electrostatics (Z-score) and the ``coverage'' of the match (fractions of the surfaces found to be in correspondence). Results are presented for 18 hypothetical proteins.

``This paper discusses the use of graph-theoretic methods for the representation and searching of three-dimensional patterns of side-chains in protein structures. The position a side-chain is represented by pseudo-atoms, and the relative positions of pairs of side-chains by the distances between them. This description of the geometry can be represented by a labelled graph in which the nodes and the edges of the graph represent the pseudo-atoms and the sets of inter-pseudo-atomic distances, respectively. Given such a representation, a protein can be searched for the presence of a user-defined query pattern of side-chains by means of a subgraph-isomorphism algorithm which is implemented in the program ASSAM.''

This paper is uses pseudo-centers to compare binding sites. ``The binding-site exposed physicochemical characteristics are described by assigning generic pseudocenters to the functional groups of the amino acids flanking a particular active site. These pseudocenters are assembled into small substructures. To find substructures with spatial similarity and appropriate chemical properties, an emergent self-organizing map is used for clustering. Two substructures which are found to be similar form the basis for an expanded comparison of the complete cavities. Preliminary results with four pairs of binding cavities show that similarities are detected correctly and motivatefurther studies.''

The presence of a query pattern in a Protein Data Bank structure can then be searched for by means of a subgraph isomorphism algorithm.

The recurring pattern is then detected using an automated search algorithm from the all-against-all pair-wise comparison data of proteins. Intra-protein pattern comparison data are used to enable detection of patterns recurring within a protein. A method has been proposed for empirical calculation of statistical significance of recurring pattern.

We proceed to rigorously apply this method to functional site recognition in three possible ways: first, we search a given functional site on a large set of complete protein structures. Second, a potential functional site on a protein of interest is compared with known binding sites, to recognize similar features. Third, a complete protein structure is searched for the presence of an a priori unknown functional site, similar to known sites.''

The first step in this method is to consider a set of atoms that closely surround a given chemical moiety. Then, to compare the spatial arrangements of such surrounding atoms in different proteins, they are translated and rotated so that the chemical moieties are superposed on each other. Spatial arrangements of surrounding atoms in a pair of proteins are judged to be similar, when there are many corresponding atoms occupying similar spatial positions.''

An additional benefit is that the method can identify functionally important residues for GO terms for which no such information is currently known.

"Recognition of spatial motifs in protein structures,"
J Mol Biol, 285, 1999, pp. 1887-1897.
This paper describes two programs: SPASM and RIGOR. SPASM matches a single structural motif (spatial arrangement of points) to a database of proteins, while RIGOR matches a single protein to many structural motifs. Each residue is represented by its CA atom and/or the centroid of its side chain. Exhaustive enumeration of possible point correspondences are enumerated exhaustively, considering points for correspondence when their residue types are within some threshold in a substitution matrix. Constraints may also be added that matching residues be in the same order in the sequence, separated by the same size gaps in the sequences, etc. For every possible set of correspondences, the point sets are superposed, and the RMSD is checked to see if it is below a threshold. Structural motifs are constructed in three ways: 1) manually, 2) all sets of residues in spatial proximity that contain only hydrophobic, only polar and charged, or mixed hydrophobic and polar/charged residues, and 3) sets of residues that all contact a single hetero-compound. Applications are shown for a few cases of main-chain recognition, active-site recongition, and metal-binding site recognition. (http://alpha2.bmc.uu.se/usf)."

This paper presents ``an approach that uses maximal common subgraph comparison and harmonic shape image matching to detect locally similar regions between two molecular surfaces augmented with properties such as the electrostatic potential or lipophilicity.'' The complexity of the problem is reduced by a set of filters that eliminate potential correpsondences between vertices with different intramolecular distances, different electrostatic potentials, different lipophilic potentials, different principal curvatures on the Connolly surfaces, different harmonic shape images for their neighborhoods on the Connolly surfaces, and different orientations of the aligned harmonic shape images with respect to the line segment between any pair of points. ``The approach was tested on dihydrofolate reductase and thermolysin inhibitors and was shown to recover the correct alignments of the compounds bound in the active sites.''

The meshes are matched using association graphs, where the electrostatic potentials and principal curvatures have to match within some threshold, as well as the intramolecular distances. No reduction of the point set is performed (e.g., using critical points). Results are shown for matching examples of two SCOP folds and for predicting the biochemical function of one hypothetical protein.

This paper uses geometric hashing to examine ``the reliability of surface comparisons in searches for active sites in proteins. Specifically, we compare the efficacy of molecular surface comparisons with comparisons of surface atoms and of C(alpha) backbone atoms. We further investigate comparisons of specific atoms, belonging to a predefined pattern of catalytic residues versus comparisons of molecular surfaces and, separately, of surface atoms. We also explore active site comparisons versus comparisons in which the entire molecular surfaces are scanned. While here we focus on the geometrical aspect of the problem, we also investigate the effect of adding residue labels in these comparisons. Our extensive studies cover the serine proteases, containing the highly conserved triad motif, and the chorismate mutases. Our results show that molecular surface comparisons work best when the similarity is high. As the similarity deteriorates, the number of potential solutions increases rapidly, making their ranking difficult, particularly when scanning entire molecular surfaces. Utilizing atomic coordinates directly appears more adequate under such circumstances.''

``A genetic algorithm (GA) is described which is used to compare the solvent-accessible surfaces of two proteins or fragments of proteins, represented by a dot surface calculated using the Connolly algorithm. The GA is used to move one surface relative to the other to locate the most similar surface region between the two. The matching process is enhanced by the use of the surface normals and shape terms provided by the Connolly program and also by a simple hydrogen-bonding descriptor and an additional shape descriptor. The algorithm has been tested in applications ranging from the comparison of small surface patches to the comparison of whole protein surfaces. Examples of the matches are given and a quantitative analysis of the quality of the matches is performed.''

Binding sites are represented by the radial extent of surfnet spheres within 3.5 angstroms of a conserved residue. The resulting spherical functions are aligned with PCA, only the highest order spherical harmonic coefficients are retained, and shape similarity is computed as the L2 distance between corresponding spherical harmonic coefficients.

``In this paper, we present an extension of our work to spherical harmonic surfaces in order to approximate molecular surfaces of both ligands and receptor-cavities and to easily check the surface-shape complementarity. The method consists of (1) finding lobes and holes on both ligand and cavity surfaces using contour maps of radius functions with spherical harmonic expansions, (2) superposing the surfaces around a given binding site by minimizing the distance between their respective expansion coefficients. This docking procedure capabilities was demonstrated by application to 35 protein-ligand complexes of known crystal structures.''

This paper presents an algorithm for representing a protein's binding site in a way that is specifically suited to molecular docking applications. Initially the protein's surface is coated with a collection of molecular fragments that could potentially interact with the protein. Each fragment, or probe, serves as a potential alignment point for atoms in a ligand, and is scored to represent that probe's affinity for the protein. Probes are then clustered by accumulating their affinities, where high affinity clusters are identified as being the ``stickiest'' portions of the protein surface. The stickiest cluster is used as a computational binding ``pocket'' for docking.

Protein-ligand binding site mapping with multiple copy simultaneous search (MCSS)

"Functionality maps of binding sites: a multiple copy simultaneous search method,"
Proteins, 11, 1991, pp. 29-34.
This is the main reference for the multiple copy simultaneous search (MCSS) method. ``A new method is proposed for determining energetically favorable positions and orientations for functional groups on the surface of proteins with known three-dimensional structure. From 1,000 to 5,000 copies of a functional group are randomly placed in the site and subjected to simultaneous energy minimization and/or quenched molecular dynamics. The resulting functionality maps of a protein receptor site, which can take account of its flexibility, can be used for the analysis of protein ligand interactions and rational drug design. Application of the method to the sialic acid binding site of the influenza coat protein, hemagglutinin, yields functional group minima that correspond with those of the ligand in a cocrystal structure.''

An overview is given of the methods currently used to locate and characterize ligand binding sites on protein surfaces, with focus on a novel approach: multiple solvent crystal structures (MSCS). In this method, the X-ray crystal structure of the target protein is solved in a variety of organic solvents. Each type of solvent molecule serves as a probe for complementary binding sites on the protein. The probe distribution on the protein surface allows the location of binding sites and the characterization of the potential ligand interactions within these sites. General aspects of the application of the MSCS method to porcine pancreatic elastase is discussed, and comparison of the results with those from X-ray crystal structures of elastase/inhibitor complexes is used to illustrate the potential of the method in aiding the process of rational drug design.''

``A protein docking study was performed for two classes of biomolecular complexes: six enzyme/inhibitor and four antibody/antigen. Biomolecular complexes for which crystal structures of both the complexed and uncomplexed proteins are available were used for eight of the ten test systems. Our docking experiments consist of a global search of translational and rotational space followed by refinement of the best predictions. Potential complexes are scored on the basis of shape complementarity and favourable electrostatic interactions using Fourier correlation theory. Since proteins undergo conformational changes upon binding, the scoring function must be sufficiently soft to dock unbound structures successfully. Some degree of surface overlap is tolerated to account for side-chain flexibility. Similarly for electrostatics, the interaction of the dispersed point charges of one protein with the Coulombic field of the other is measured rather than precise atomic interactions. We tested our docking protocol using the native rather than the complexed forms of the proteins to address the more scientifically interesting problem of predictive docking. In all but one of our test cases, correctly docked geometries (interface Calpha RMS deviation

``A computationally efficient method is presented - `fast rotational matching' or FRM - that significantly accelerates the search of the three rotational degrees of freedom (DOF) in biomolecular matching problems. This method uses a suitable parametrization of the three-dimensional rotation group along with spherical harmonics, which allows efficient computation of the Fourier Transform of the rotational correlation function. Previous methods have used Fourier techniques only for two of the rotational DOFs, leaving the remaining angle to be determined by an exhaustive search. Here for the first time a formulation is presented that makes it possible to Fourier transform all three rotational DOFs, resulting in notable improvements in speed. Applications to the docking of atomic structures into electron-microscopy maps and the molecular-replacement problem in X-ray crystallography are considered.''

"Fast rotational matching of rigid bodies by fast Fourier transform acceleration of five degrees of freedom,"
Acta Cryst., D59, 2003, pp. 1371-1376.
``The `fast rotational matching' method is extended to the full six-dimensional (rotation and translation) matching scenario between two three-dimensional objects. By recasting this problem into a formulation involving five angles and just one translational parameter, it was possible to accelerate, by means of fast Fourier transforms, five of the six degrees of freedom of the problem. This method was successfully applied to the docking of atomic structures of components into three-dimensional low-resolution density maps. Timing comparisons performed with our method and with `fast translational matching' (the standard way to accelerate the translational parameters utilizing fast Fourier transforms) demonstrates that the performance gain can reach several orders of magnitude, especially for large map sizes. This gain can be particularly advantageous for spherical- and toroidal-shaped maps, since the scanning range of the translational parameter would be significantly constrained in these cases. The method can also be harnessed to the complementary surface (or `exterior docking') problem and to pattern recognition in image processing.''

De novo methods have also been used to modify and significantly improve the binding affinity of an HIV protease inhibitor. Work continues in the improvement of methods for the de novo design of compounds which fit and chemically complement a binding site. De novo algorithms that generate only synthetically feasible structures have also been reported. In addition, methods are being developed for the automatic computer generation of virtual molecular libraries which can be searched to identify molecules to match a pharmacophore or fit into a binding site.''

``BACKGROUND: A principal goal of structure prediction is the elucidation of function. We have studied the ability of computed models to preserve the microenvironments of functional sites. In particular, 653 model structures of a calcium-binding protein (generated using an ab initio folding protocol) were analyzed, and the degree to which calcium-binding sites were recognizable was assessed. RESULTS: While some model structures preserve the calcium-binding microenvironments, many others, including some with low root mean square deviations (rmsds) from the crystal structure of the native protein, do not. There is a very weak correlation between the overall rmsd of a structure and the preservation of calcium-binding sites. Only when the quality of the model structure is high (rmsd less than 2 A for atoms in the 7 A local neighborhood around calcium) does the modeling of the binding sites become reliable. CONCLUSIONS: Protein structure prediction methods need to be assessed in terms of their preservation of functional sites. High-resolution structures are necessary for identifying binding sites such as calcium-binding sites.''

The expectation is that any similarity in reaction chemistry shared by enzyme homologues is mediated by common functional groups conserved through evolution. However, detailed enzyme studies have revealed the flexibility of many active sites, in that different functional groups, unconserved with respect to position in the primary sequence, mediate the same mechanistic role. Nevertheless, the catalytic atoms might be spatially equivalent. More rarely, the active sites have completely different locations in the protein scaffold. This variability could result from: (1) the hopping of functional groups from one position to another to optimize catalysis; (2) the independent specialization of a low-activity primordial enzyme in different phylogenetic lineages; (3) functional convergence after evolutionary divergence; or (4) circular permutation events.
