WebCarbonic anhydrase is a metalloenzyme that accelerates the interconversion between CO 2 and H 2 O, and H 2 CO 3 (carbonic acid) and its dissociative ions (HCO 3 − and H +). … WebCarbonic anhydrase (CA; carbonate hydro-lyase, EC 4.2.1.1) is a zinc-containing enzyme that catalyzes the reversible hydration of carbon dioxide: CO2+ H2O<-->HCO3(-)+H+. …
WebJun 30, 2009 · The generally accepted catalytic mechanism of carbonic anhydrase ( 13) is described by a 3-step kinetic scheme: ( i) a Zn-OH − moiety catalyzes the interconversion of CO 2 to HCO 3−, leaving a water molecule as the fourth zinc ligand ( Eq. 1 ); ( ii) a proton is then transferred from the zinc-bound water to the imidazole ring of His-64 ( Eq ...
