| Short Name | Peptidase_S66_N |
| description | This entry includes proteins belonging to the MEROPS peptidase family S66, such as muramoyl-tetrapeptide carboxypeptidase and the microcin c7 self-immunity protein . Muramoyl-tetrapeptide carboxypeptidase, also known as LD-carboxypeptidase A, hydrolyses a peptide bond between a di-basic amino acid and the C-terminal D-alanine in the tetrapeptide moiety in peptidoglycan. This cleaves the bond between an L- and a D-amino acid. This activity has a role in murein recycling [, ]. The structure of Pseudomonas aeruginosa LD-carboxypeptidase showed that the enzyme consists of an N-terminal β-sheet and a C-terminal β-barrel domain []. This entry represents the N-terminal domain. |
