Enzyme Information

3.4.16.4

Serine-type D-Ala-D-Ala carboxypeptidase.

based on mapping to UniProt P39045

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 group of bacterial enzymes, membrane-bound. -!- Inhibited by beta-lactam antibiotics, which acylate the active site serine in the enzyme. -!- Distinct from EC 3.4.17.14. -!- Belongs to peptidase families S11, S12 and S13.
