CC   -!- FUNCTION: Catalyzes the synthesis of alpha-ribazole-5'-phosphate from
CC       nicotinate mononucleotide (NAMN) and 5,6-dimethylbenzimidazole (DMB).
CC       {ECO:0000255|HAMAP-Rule:MF_00230}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=5,6-dimethylbenzimidazole + nicotinate beta-D-ribonucleotide =
CC         alpha-ribazole 5'-phosphate + H(+) + nicotinate;
CC         Xref=Rhea:RHEA:11196, ChEBI:CHEBI:15378, ChEBI:CHEBI:15890,
