SSEP-2.0: Secondary Structural Elements of Proteins

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/.
