Zn
each monomer binds one Zn-atom, far away from catalytic site, plays structural role
Zn2+
-
has a structural role rather than a catalytic one, lies at the center of a tetrahedron. The side chains of H56 and H97 are at a distance of 2.0 A from the metal ion, while the oxygen atom of the carboxylic side chain of D98 coordinates the zinc ion in a monodentate manner. Water molecule at 2.7 A from the metal ion
