SSEP-2.0: Secondary Structural Elements of Proteins

Abstract

The Secondary Structural Elements of Proteins (SSEP) database is an integrated and comprehensive knowledge base for accessing information related to all the secondary-structural elements present in non-redundant (25 and 90%) protein chains. The new version 2.0 of the database contains 2485 and 8595 protein chains from the 25 and 90% non-redundant data sets, respectively. The necessary web interfaces have been developed that enable users to visualize the three-dimensional structure of the secondary-structural element in the client machine using the free molecular-visualization program RASMOL. This source is updated at regular intervals and can be accessed through the bioinformatics web server at the URL http://cluster.physics.iisc.ernet.in/ssep or http://144.16.71.148/ssep/.
