CC -!- FUNCTION: Catalyzes the ATP-dependent amidation of the two carboxylate
CC groups at positions a and c of cobyrinate, using either L-glutamine or
CC ammonia as the nitrogen source. {ECO:0000256|HAMAP-Rule:MF_00027}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=2 ATP + cob(II)yrinate + 2 H2O + 2 L-glutamine = 2 ADP +
CC cob(II)yrinate a,c diamide + 2 H(+) + 2 L-glutamate + 2 phosphate;
CC Xref=Rhea:RHEA:26289, ChEBI:CHEBI:15377, ChEBI:CHEBI:15378,
CC ChEBI:CHEBI:29985, ChEBI:CHEBI:30616, ChEBI:CHEBI:43474,
CC ChEBI:CHEBI:58359, ChEBI:CHEBI:58537, ChEBI:CHEBI:58894,
CC ChEBI:CHEBI:456216; EC=6.3.5.11; Evidence={ECO:0000256|HAMAP-
CC Rule:MF_00027};
CC -!- COFACTOR:
CC Name=Mg(2+); Xref=ChEBI:CHEBI:18420;
CC Evidence={ECO:0000256|ARBA:ARBA00001946,
CC ECO:0000256|HAMAP-Rule:MF_00027};
CC -!- PATHWAY: Cofactor biosynthesis; adenosylcobalamin biosynthesis;
CC cob(II)yrinate a,c-diamide from sirohydrochlorin (anaerobic route):
CC step 10/10. {ECO:0000256|HAMAP-Rule:MF_00027}.
CC -!- DOMAIN: Comprises of two domains. The C-terminal domain contains the
CC binding site for glutamine and catalyzes the hydrolysis of this
CC substrate to glutamate and ammonia. The N-terminal domain is
CC anticipated to bind ATP and cobyrinate and catalyzes the ultimate
CC synthesis of the diamide product. The ammonia produced via the
CC glutaminase domain is probably translocated to the adjacent domain via
CC a molecular tunnel, where it reacts with an activated intermediate.
CC {ECO:0000256|HAMAP-Rule:MF_00027}.
CC -!- MISCELLANEOUS: The a and c carboxylates of cobyrinate are activated for
CC nucleophilic attack via formation of a phosphorylated intermediate by
CC ATP. CbiA catalyzes first the amidation of the c-carboxylate, and then
CC that of the a-carboxylate. {ECO:0000256|HAMAP-Rule:MF_00027}.
CC -!- SIMILARITY: Belongs to the CobB/CbiA family. {ECO:0000256|HAMAP-
CC Rule:MF_00027}.
