Carbonic Anhydrase, Superoxide dismutase enzyme activity is related with which element?

Carbonic Anhydrase and superoxide dismutase enzyme activity are related to the Zinc element.
Zinc activates enzymes of protein metabolism, and is a part of carbonate dehydratase, and superoxide dismutase.
The zinc ion creates the catalytic center in Superoxide dismutase.
Carbonate dehydratases form a family of enzymes that catalyzes the interconversion between carbon dioxide and water and dissociated ions of carbonic acid. The active site of most carbonic anhydrases contains a zinc ion.
