Comments [?]

FUNCTION	Joins adenosylcobinamide-GDP and alpha-ribazole to generate adenosylcobalamin (Ado-cobalamin). Also synthesizes adenosylcobalamin 5'-phosphate from adenosylcobinamide-GDP and alpha-ribazole 5'- phosphate.
CATALYTIC ACTIVITY	Reaction=adenosylcob(III)inamide-GDP + alpha-ribazole = adenosylcob(III)alamin + GMP + H(+); Xref=Rhea:RHEA:16049, ChEBI:CHEBI:10329, ChEBI:CHEBI:15378, ChEBI:CHEBI:18408, ChEBI:CHEBI:58115, ChEBI:CHEBI:60487; EC=2.7.8.26;
CATALYTIC ACTIVITY	Reaction=adenosylcob(III)inamide-GDP + alpha-ribazole 5'-phosphate = adenosylcob(III)alamin 5'-phosphate + GMP + H(+); Xref=Rhea:RHEA:23560, ChEBI:CHEBI:15378, ChEBI:CHEBI:57918, ChEBI:CHEBI:58115, ChEBI:CHEBI:60487, ChEBI:CHEBI:60493; EC=2.7.8.26;
COFACTOR	Name=Mg(2+); Xref=ChEBI:CHEBI:18420;
PATHWAY	Cofactor biosynthesis; adenosylcobalamin biosynthesis; adenosylcobalamin from cob(II)yrinate a,c-diamide: step 7/7.
