Reference Data
Summary	Carbonic anhydrase (CA) is an enzyme that catalyses rapid conversion of carbon dioxide to bicarbote and protons (CO2 + H2O <-> HCO3- + H+). Most carbonic anhydrases contain a zinc ion in their active site and the primary function of this enzyme is known to maintain acid-base balance in blood and other tissues, and to help transport carbon dioxide of tissues. Carbonic anhydrases have been found in all kingdoms of life. Recombint carbonic anhydrase fused to His-tag, was expressed in E.coli and purified by conventiol chromatography techniques.
