comments
This enzyme belongs to the peptidase family-C12.
According to the literature & Swissprot data, this enzyme catalyzes hydrolyses of amide bond (including peptide bond), thioester bond, and carboxlic ester bond.
According to the literature [4] & [8], this enzyme has got a catalytic triad composed of Cys/His/Asp and an oxyanion hole, made up by mainchain amide of the cysteine residue and sidechain amide of Gln.
The catalytic mechanism is also similar to other cysteine proteases, in which cysteine acts as a nucleophile, and histidine acts as a general acid-base.
