Metallocarboxypeptidase-like, propeptide
IPR036990
Definition
The peptidases are synthesised as inactive molecules, zymogens, with propeptides that must be removed by proteolytic cleavage to activate the enzyme. Structural studies of carboxypeptidases A and B reveal the propeptide to exist as a globular domain, followed by an extended α-helix; this shields the catalytic site, without specifically binding to it, while the substrate-binding site is blocked by making specific contacts [[cite:PMID:7674922], [cite:PMID:1548696]]. This entry represents a propeptide associated with peptidases belonging to MEROPS peptidase family M14A. It is found in the carboxypeptidases A PMID:9384570 and B PMID:12162965, and in fungal putative metallocarboxypeptidase Ecm14.
