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:0000255|HAMAP-Rule:MF_00028}.
CC   -!- PATHWAY: Cofactor biosynthesis; adenosylcobalamin biosynthesis.
CC       {ECO:0000255|HAMAP-Rule:MF_00028}.
CC   -!- SIMILARITY: Belongs to the CobB/CobQ family. CobQ subfamily.
CC       {ECO:0000255|HAMAP-Rule:MF_00028}.
