3.4.24.23

Accepted name:

matrilysin

Reaction:

Cleavage of Ala¹⁴┼Leu and Tyr¹⁶┼Leu in B chain of insulin. No action on collagen types I, II, IV, V. Cleaves gelatin chain α2(I) > α1(I)

Other name(s):

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
