This domain is composed of three alpha helices [1]. This domain is found at the N or C terminus of a variety of enzymes involved in bacterial cell wall degradation [2]. This domain may have a general peptidoglycan binding function. This family is found N-terminal to the catalytic domain of matrixins [3]. The domain is found to bind peptidoglycan experimentally [4].
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.
