RT "Function of individual gut microbiota members based on whole genome
RT sequencing of pure cultures obtained from chicken caecum.";
RL Submitted (APR-2017) to the EMBL/GenBank/DDBJ databases.
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|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|HAMAP-Rule:MF_00028}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
CC {ECO:0000313|EMBL:OUQ27522.1}.
