CC -!- FUNCTION: Catalyzes amidations at positions B, D, E, and G on
CC adenosylcobyrinic A,C-diamide. NH(2) groups are provided by glutamine,
CC and one molecule of ATP is hydrogenolyzed for each amidation.
CC {ECO:0000256|ARBA:ARBA00025166, ECO:0000256|HAMAP-Rule:MF_00028}.
CC -!- PATHWAY: Cofactor biosynthesis; adenosylcobalamin biosynthesis.
CC {ECO:0000256|ARBA:ARBA00004953, ECO:0000256|HAMAP-Rule:MF_00028}.
CC -!- SIMILARITY: Belongs to the CobB/CobQ family. CobQ subfamily.
CC {ECO:0000256|ARBA:ARBA00006205, ECO:0000256|HAMAP-Rule:MF_00028}.
