IUBMB Enzyme Nomenclature


Accepted name: membrane-type matrix metalloproteinase-1

Reaction: Endopeptidase activity. Activates progelatinase A by cleavage of the propeptide at Asn37Leu. Other bonds hydrolysed include Gly35Ile in the propeptide of collagenase 3, and Asn341Phe, Asp441Leu and Gln354Thr in the aggrecan interglobular domain

Other name(s): matrix metalloproteinase 14

Comments: In peptidase family M10, but, unlike most members of the family, is membrane-anchored. Believed to play an important role in the activation of progelatinase A at cell surfaces.
