EC 18.104.22.168 - Serine-type D-Ala-D-Ala carboxypeptidase
IntEnz Enzyme Nomenclature
- Preferential cleavage: (Ac)2-L-Lys-D-Ala┼D-Ala. Also transpeptidation of peptidyl-alanyl moieties that are N-acyl substituents of D-alanine.
A membrane-bound, bacterial enzyme inhibited by penicillin and other β-lactam antibiotics, which acylate the active site serine. Examples are known from peptidase families S11, S12 and S13. Distinct from zinc D-Ala-D-Ala carboxypeptidase, EC 22.214.171.124.
