Zn1, coordinated by three histidine residues, acts as a major constituent of oxyanion hole to stabilize tetrahedral intermediate. It also acts as a Lewis acid for interaction with lactam carbonyl in Michaelis complex. Zn1 also acts to suppress the pka of the hydrolytic water to (~5-6) to facilitate it's nucleophillic role.
