Database of homology-derived protein structures and the structural meaning of sequence alignment. References Publications referenced by this paper.

SRS–an indexing and retrieval tool for flat file data libraries. The sets of representative folds contain a maximal number fasp protein folds where no pair is allowed to have a larger fraction of structurally equivalent residues than a given threshold percentage. All alignments are based purely on the 3-D co-ordinates of the proteins and are derived by an automatic structure comparison program Dali.

Identification and classification of protein fold families.

World Wide Web Query language Sequence alignment. Protein structure datbase by alignment of distance matrices. The structure comparison program Dali 9 defines the extent of the common structural core by maximizing the agreement of intra molecular CA-CA distances. The alignments are constrained to be sequential as this is biologically meaningful though not imposed by the Dali method.

The sequence-representative set is derived using algorithm 1 of ref. Searching protein structure databases has come of age. Kindly report any problems to the authors by e-mail.

The database provides a rich source of information for the study of both divergent and cssp aspects of the evolution of protein folds and defines useful test sets and a standard of truth for assessing the correctness of sequence-sequence or sequence-structure alignments.

For example, Figure 2 shows how the first C2 domain of synaptotagmin I PDB entry 1RSYwhich presented a new calcium-binding fold 7is firmly anchored in a large structural class that contains beta-sandwich proteins with topological similarity to immunoglobulin-like domains and blue copper proteins.

Only structurally equivalent blocks are shown; the middle fss; of the alignment has been omitted in order to highlight the conserved sequence signatures near the N- and C-termini. In this example, 31 PDB chains clustered into the sequence family represented by bovine pancreatic trypsin inhibitor 9PTI have been extracted from the table.

The scoring function was deliberately designed to allow inter-domain conformational flexibility; hence, positional root mean square deviations for the corresponding rigid-body superimpositions are often higher than for comparison methods that put an absolute upper limit on inter molecular positional deviations.

Most newly determined protein rssp can be classified into families by sequence homology. Searching protein structure databases has come of age. All such comparisons are based purely on the 3D co-ordinates of the proteins and are derived by automatic daatbase structure comparison programs.
