General annotation (Comments)

Function	Responsible for the amidation of carboxylic groups at position A and C of either cobyrinic acid or hydrogenobrynic acid. NH2 groups are provided by glutamine, and one molecule of ATP is hydrogenolyzed for each amidation. HAMAP MF_00027
Pathway	Cofactor biosynthesis; adenosylcobalamin biosynthesis; cob(II)yrinate a,c-diamide from sirohydrochlorin (anaerobic route): step 10/10. HAMAP MF_00027
Sequence similarities	Belongs to the CobB/CobQ family. CobB subfamily. Contains 1 GATase cobBQ-type domain.
