CC -!- FUNCTION: Catalyzes cobalt insertion in the corrin ring.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=ATP + Co(2+) + H2O + hydrogenobyrinate a,c-diamide = ADP +
CC cob(II)yrinate a,c diamide + 5 H(+) + phosphate;
CC Xref=Rhea:RHEA:15341, ChEBI:CHEBI:15377, ChEBI:CHEBI:15378,
CC ChEBI:CHEBI:30616, ChEBI:CHEBI:43474, ChEBI:CHEBI:48828,
CC ChEBI:CHEBI:58537, ChEBI:CHEBI:77874, ChEBI:CHEBI:456216; EC=6.6.1.2;
CC -!- PATHWAY: Cofactor biosynthesis; adenosylcobalamin biosynthesis;
CC cob(II)yrinate a,c-diamide from precorrin-2 (aerobic route): step
CC 10/10.
CC -!- SUBUNIT: Heterotrimer of CobN, CobS and CobT.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000305}.
CC -!- CAUTION: Was originally thought to originate from Pseudomonas
CC denitrificans, but similarity searches show that the sequence is much
CC closer to Sinorhizobium. The entry's taxonomy has been changed.
CC {ECO:0000305}.
