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         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}.
