Aspartyl proteases use an aspartic acid residue to activate a water molecule and another aspartic acid residue to align the peptide for attack. Metalloproteases use a metal ion to activate a water molecule.

WebCysteine proteases, also known as papain-like or thiol proteases, have a catalytic dyad comprising Cys and His residues in close proximity that interact with each other. During proteolysis, the Cys sulfhydryl group acts as a nucleophile to initiate attack on the carbonyl carbon of the peptide bond to be hydrolyzed. WebNov 16, 2024 · The COVID M pro (main protease) is a cysteine protease inhibitor, meaning that it uses the thiol (S-H) group on the amino acid cysteine to catalyze the cleavage of the protein's amide bond.
