Our lab mainly works on membrane proteins (specifically on porins). Development of a database of known and probable porins was the work I have started with which resulted in PRNDS.It runs on PostgreSQL RDBMS backend on top of a linux box. This database is not only a repository of probable porins representing 8,16,18 and 22 stranded porins but they are also ranked based on a consensus based approach which makes it useful for target selection for structural genomics initiative and to get better insights towards general porin characteristics by using the probable porin sequences in the database. Presently there are 3182 sequences classified as 8,16,18 and 22 stranded probable porins which are derived from Swissprot. I am working towards a second release of the database with more features and analysis.
