PPT-DB

The PPT-DB is a database of databases. It houses more than 20 carefully curated databases, each of which contain commonly predicted protein property information. PPT-DB is designed to serve two purposes. First it is intended to serve as a centralized, up-to-date, freely downloadable, easily queried and carefully curated repository of predictable or "derived" protein property data (such as secondary structures, transmembrane helices, signal peptides, B-factors, disulfide pairings, contact order, folding rates etc.). In this role, PPT-DB can serve as a one-stop, fully standardized repository that developers may access to obtain the required training, testing and validation data needed for almost any kind of protein property prediction program they may wish create. The second role that PPT-DB can play is as a tool for homology-based protein property prediction. Users (as opposed to developers) may query PPT-DB with a sequence of interest and have a specific property (say secondary..
