Type 1 glutamine amidotransferase (GATase1) domain found in Cobyrinic Acid a,c-Diamide Synthase
Type 1 glutamine amidotransferase (GATase1) domain found in Cobyrinic Acid a,c-Diamide Synthase. CobB plays a role in cobalamin biosythesis catalyzing the conversion of cobyrinic acid to cobyrinic acid a,c-diamide. CobB belongs to the triad family of amidotransferases. Two of the three residues of the catalytic triad that are involved in glutamine binding, hydrolysis and transfer of the resulting ammonia to the acceptor substrate in other triad aminodotransferases are conserved in CobB.
