Factor Xa subsite mapping by proteome-derived peptide libraries improved using WebPICS, a resource for proteomic identification of cleavage sites

Abstract Proteomic identification of protease cleavage site specificity (PICS) is a recent proteomic approach for the easy mapping of protease subsite preferences that determines both the prime- and non-prime side specificity concurrently. Here we greatly facilitate user access by providing an automated and simple web-based data-analysis resource termed WebPics ( We demonstrate the utility of WebPics analysis of PICS data by determining the substrate specificity of factor Xa from P6-P6’, an important blood coagulation protease that proteolytically generates thrombin from prothrombin. PICS confirms existing data on non-prime site specificity and refines our knowledge of factor Xa prime-site selectivity.
