Removal of carbon dioxide becomes one of important research area in recent green era. But, instead of just removal, carbon dioxide can be utilized as a good resource to obtain high valuable chemicals. Many marine organisms use carbon dioxide as useful source for their lifes. Some organisms fix carbon dioxide to synthesize glucose and some produce calcium carbonate shells to protect their bodies. In any cases, initial step is hydration of carbon dioxide (CO2 + H2O → HCO3-). In this step, key material is carbonic anhydrase (CA) because uncatalyzed interconversion between carbon dioxide and bicarbonate is very slow. CA is a zinc-containing metalloenzyme, catalyzing the reversible hydration of carbon dioxide. In the present work, we will present the use of recombinant CA enzymes to convert carbon dioxide biologically to valuable chemical, calcium carbonate.
