The reaction direction shown, that is, A + B ↔ C + D versus C + D ↔ A + B, is in accordance with the Enzyme Commission system.
Mass balance status: Undetermined; a substrate lacks a chemical formula
Enzyme Commission Primary Name: membrane-type matrix metalloproteinase-1
Enzyme Commission Synonyms: matrix metalloproteinase 14
Enzyme Commission Summary:
Endopeptidase activity. Activates procollagenase by cleavage of the propeptide at Asn37|Leu. Other bonds hydrolysed include Gly35|Ile in the propeptide of collagenase 3, and Asn341|Phe, Asp441|Leu and Gln354|Thr in the aggrecan interglobular domain.
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.
