Carbonic Anhydrase: Mechanism, Structure and Importance in Higher Plants

Carbonic anhydrase, a zinc-containing metalloenzyme, is an essential enzyme for photosynthesis because of its property to convert CO2 to HCO3- reversibly. Besides its role in carboxylation, it plays an important part in stomatal closure in plant leaves. Carbonic anhydrase is the second most abundant enzyme in the chloroplast representing about 20.1% of total soluble protein and is one of the fastest acting enzymes in biological system. Carbon Dioxide being main Constituent of Global warming is directly related to Carbonic anhydrase activity in Plants This review attempts to present a picture of the physiological role of carbonic anhydrase in plants, in the fixation of greenhouse gas like CO2 from the atmosphere and its role as a biochemical marker for carbon sequestration
