HHsearch alignment for GI: 254780420 and conserved domain: cd01750

>cd01750 GATase1_CobQ Type 1 glutamine amidotransferase (GATase1) domain found in Cobyric Acid Synthase (CobQ). Type 1 glutamine amidotransferase (GATase1) domain found in Cobyric Acid Synthase (CobQ). CobQ plays a role in cobalamin biosythesis. CobQ catalyses amidations at positions B, D, E, and G on adenosylcobyrinic A,C-diamide in the biosynthesis of cobalamin. CobQ 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 CobQ.
