CC -!- FUNCTION: Joins adenosylcobinamide-GDP and alpha-ribazole to generate
CC adenosylcobalamin (Ado-cobalamin). Also synthesizes adenosylcobalamin
CC 5'-phosphate from adenosylcobinamide-GDP and alpha-ribazole 5'-
CC phosphate. {ECO:0000255|HAMAP-Rule:MF_00719}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=adenosylcob(III)inamide-GDP + alpha-ribazole =
CC adenosylcob(III)alamin + GMP + H(+); Xref=Rhea:RHEA:16049,
CC ChEBI:CHEBI:10329, ChEBI:CHEBI:15378, ChEBI:CHEBI:18408,
CC ChEBI:CHEBI:58115, ChEBI:CHEBI:60487; EC=2.7.8.26;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_00719};
CC -!- CATALYTIC ACTIVITY:
CC Reaction=adenosylcob(III)inamide-GDP + alpha-ribazole 5'-phosphate =
CC adenosylcob(III)alamin 5'-phosphate + GMP + H(+);

CC ChEBI:CHEBI:58115, ChEBI:CHEBI:60487, ChEBI:CHEBI:60493; EC=2.7.8.26;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_00719};
CC -!- COFACTOR:
CC Name=Mg(2+); Xref=ChEBI:CHEBI:18420;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_00719};
CC -!- PATHWAY: Cofactor biosynthesis; adenosylcobalamin biosynthesis;
CC adenosylcobalamin from cob(II)yrinate a,c-diamide: step 7/7.
CC {ECO:0000255|HAMAP-Rule:MF_00719}.
CC -!- SUBCELLULAR LOCATION: Cell inner membrane {ECO:0000255|HAMAP-
CC Rule:MF_00719}; Multi-pass membrane protein {ECO:0000255|HAMAP-
CC Rule:MF_00719}.
CC -!- SIMILARITY: Belongs to the CobS family. {ECO:0000255|HAMAP-
CC Rule:MF_00719}.
