Shown is the enzyme Carbonic Anhydrase II which falls under α-Family of Carbonic Anhydrases. As the name suggest Carbonic Anhydrases are a class of enzymes which catalyze the reversible conversion of carbondioxide to the bicarbonate and proton. Due to this unique property they play a key role in maintaining the acid-base balance of blood and several other tissues.
The active site of the enzyme is depicted here, which has three histidine residues coordinated to the zinc metal.
