General description

Recombinant, human caspase-2 expressed in E. coli as a single polypeptide chain. Subsequently undergoes spontaneous auto-processing to yield the native active enzyme. Useful for the study of enzyme regulation, cleavage of target substrates, and inhibitor screening. Cleavage sites are located at Asp316, Asp330, and possibly Asp152. MW: 12000 and 19000.
