Peroxiredoxin classification index

PeroxiRedoxin classification indEX (PREX) is a database of peroxiredoxins (Prxs) classified into one of six distinct subfamilies. Classification relies on the Deacon Active Site Profiling (DASP) approach that utilizes a position specific scoring matrix (PSSM) created from aligned signatures (built from sequence fragments surrounding active sites of structurally-characterized Prx group members) to search sequence databases.
