Zinc plays an important role in calcium. Calcium uses zinc as a enzyme catalysis and to maintain structure ( Alberts, Nadassy & Wodak, 1998). Zinc is able to maintain the structure of calcium by stabilizing its folded conformation. Zinc will also bind to the carboxyl group of the substrate in order to stabilize the enzyme-substrate complex. The zinc sites exhibit a tetrahedral geometry. At the catalytic site, the zinc ion will act as a Lewis acid (McCall, Huang & Fierce, 2000). Zinc can be classified as a metalloenzyme, which is a metal ion catalyst. This catalytic zinc site is located at the active site of calcium.This has further been confirmed by X-ray crystallography and enzymological studies of calciums active site. This concludes my findings
