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,
CC         ChEBI:CHEBI:32544, ChEBI:CHEBI:57502, ChEBI:CHEBI:57918; EC=2.4.2.21;
CC         Evidence={ECO:0000255|HAMAP-Rule:MF_00230};
CC   -!- PATHWAY: Nucleoside biosynthesis; alpha-ribazole biosynthesis; alpha-
CC       ribazole from 5,6-dimethylbenzimidazole: step 1/2. {ECO:0000255|HAMAP-
CC       Rule:MF_00230}.
