The proteasome is a multicatalytic proteinase complex which is characterized by its ability to cleave peptides with Arg, Phe, Tyr, Leu, and Glu adjacent to the leaving group at neutral or slightly basic pH. The proteasome has an ATP-dependent proteolytic activity. This subunit has a trypsin-like activity. Source: Recombinant protein corresponding to aa1-201 from human PSMB2, fused to GST-Tag at N-terminal expressed in E. coli.
