Zinc
-
isoenzyme A2 contains 2.7 mol of zinc per mol of enzyme, isoenzyme b2 contains 1.9 mol of zinc per mol of enzyme, isoenzyme C2 contains 3.2 mol of zinc per mol of enzyme. A and C subunits each contain two atoms of zinc, with at least one being involved catalytically, the b subunit probably contains a single non-catalytic zinc atom
Zn2+
catalytic zinc ion
Zn2+
-
1 catalytic and 1 structural zinc ion per subunit
Zn2+
-
2 atoms are included in each 40 kDa subunit, while one of the zinc ions is considered to serve a structural function only, the other zinc ion functions as a Lewis acid and activates the substrate in the active site, which is located in a cleft between the catalytic and the coenzyme binding domain
