Leu and Tyr16Leu in B chain of insulin. No action on collagen types I, II, IV, V. Cleaves gelatin chain α2(I) > α1(I)
Reaction: Cleavage of Ala14Leu and Tyr16Leu in B chain of insulin. No action on collagen types I, II, IV, V. Cleaves gelatin chain α2(I) > α1(I)
Other names: matrin; uterine metalloendopeptidase; matrix metalloproteinase 7; putative (or punctuated) metalloproteinase-1; matrix metalloproteinase pump 1; MMP 7; PUMP-1 proteinase; PUMP; metalloproteinase pump-1; putative metalloproteinase; MMP
Comments: Found in rat uterus; at 19 kDa, the smallest member of peptidase family M10 (interstitial collagenase family). Similar in specificity to stromelysin, but more active on azocoll
