| Endopeptidases Peptide Peptidohydrolases | Proteases | Proteinases A subclass of PEPTIDE HYDROLASES. They are classified primarily by their catalytic mechanism. Specificity is used only for identification of individual enzymes. They comprise the SERINE ENDOPEPTIDASES, EC 3.4.21; CYSTEINE ENDOPEPTIDASES, EC 3.4.22; ASPARTIC ENDOPEPTIDASES, EC 3.4.23, METALLOENDOPEPTIDASES, EC 3.4.24; and a group of enzymes yet to be assigned to any of the above sub-classes, EC 3.4.99.
