Zinc D-Ala-D-Ala carboxypeptidase (EC 3.4.17.14, Zn2+ G peptidase, D-alanyl-D-alanine hydrolase, D-alanyl-D-alanine-cleaving carboxypeptidase, DD-carboxypeptidase, G enzyme, DD-carboxypeptidase-transpeptidase) is an enzyme.[1][2][3] This enzyme catalyses the following chemical reaction
- Cleavage of the bond: (Ac)2-L-lysyl-D-alanyl--D-alanine
This is a zinc enzyme. Catalyses carboxypeptidation but not transpeptidation reactions involved in bacterial cell wall metabolism.
