Chains	Enzyme Name	Description	Catalytic Residues
A	zinc D-Ala-D-Ala carboxypeptidase M-CSA #585	The zinc D-Ala-D-Ala carboxypeptidase belongs to the peptidase M15 family and hydrolyses the C-terminal peptide bond of the peptides of general structure R-DAla-D-Xaa, it is secreted by Streptomyces albus G. The lytic activity of the enzyme and its extracellular location suggest that it might be used by Streptomyces for fighting competitors in its ecological niche, since the enzyme does not hydrolyse the Streptomyces peptidoglycan.
