Carbonic anhydrase（carbonate dehydratase) is a family of metalloenzymes（enzymes that contain one or more metal atoms as a functional component of the enzyme) that catalyze the rapid（and reversible) conversion of carbon dioxide to bicarbonate and protons， a reaction that occurs rather slowly in the absence of a catalyst. Carbonic anhydrase greatly increases the rate of the reaction， with typical catalytic rates of the different forms of this enzyme ranging between 104 and 106 reactions per second. The active site of most carbonic anhydrases contains a zincion. CAIII is a cytoplasmic isoenzyme， but is released into the circulation following injury.
