A CLOSER LOOK AT THE ACTIVE SITE OF GAMMA-CARBONIC ANHYDRASES: HIGH RESOLUTION CRYSTALLOGRAPHIC STUDIES OF THE CARBONIC ANHYDRASE FROM METHANOSARCINA THERMOPHILA
1qrf is a 1 chain structure with sequence from Methanosarcina thermophila. Full crystallographic information is available from OCA. For a guided tour on the structure components use FirstGlance.
CAH_METTT Reversible hydration of carbon dioxide. Important for growth on acetate (PubMed:8041719). As a probably extracellular enzyme, it may support a H(+)/CH(3)COO(-) symport mechanism and/or conversion of CO(2) to HCO(3)(-), removing excess CO(2) produced by growth on acetate (Probable).[1][2][3][4]
