WebAn interesting feature of this protease is its broad specificity for peptide bonds, allowing a high degree of protein hydrolysis to be achieved. But this enzyme, like other cysteine proteases, has a preference for an amino acid containing a large hydrophobic side chain at position P2 and does not accept Val at P1' [53].

[1] The second histidine is not as effective an acid as the more common aspartate or glutamate, leading to a lower catalytic efficiency. In some enzymes, the acid member of the triad is less necessary and some act only as a dyad.
