The Zn ion which is involved in the catalytic activity is the Zn999. In a publication (http://www.ncbi.nlm.nih.gov/pmc/articles/PMC394940/?page=2) which studies the catalytic domain of MMP8 thanks to the Pro-Leu-Gly-hydroxylamine inhibitor, this ion is penta-coordinated with: His197, His201 and His207 of MMP8 and with the carbonyl and the hydroxyl oxygen of the hydroxamic acid moiety of the inhibitor. | Zn999 | ||
