Database of structural motifs in proteins

The database of structural motifs in proteins (DSMP) contains data relevant to helices, B-turns, gamma-turns, beta-hairpins, psi-loops, beta-alpha-bet a motifs, beta-sheets, beta-strands and disulphide bridges extracted from a ll proteins in the Protein Data Bank primarily using the PROMOTIF program a nd implemented as a web-based network service using the SRS. The data corre sponding to the structural motifs includes; sequence, position in polypepti de chain, geometry, type, unique code, keywords and resolution of crystal s tructure. This data is available for a representative data set of 1028 prot ein chains and also for all 10 213 proteins in the Protein Data Bank. The t hree-dimensional coordinates for all structural motifs (except sheet and di sulphide bridge) are also available for the representative data set. Using features in SRS, DSMP can be queried to extract information from one or mor e structural motifs that may be useful for sequence-structure analysis, pre diction, modelling or design.
