Carbonic Anhydrase

Carbonic anhydrase (CA) is an enzyme present in many organisms including plants, animals, fungi, bacteria, and archaea. It is responsible for catalyzing the interconversion of bicarbonate (HCO3-) and carbon dioxide (CO2). In most organisms, CAs play an important role in acid-base balance and transport of CO2 away from the cell. In organisms that undergo photosynthesis or house photosynthetic organisms within their tissue (e.g. some sea anemones), CAs have been shown to play an important role in moving HCO3- and CO2 from the external environment to the center of photosynthesis.
