CC -!- FUNCTION: Catalyzes the synthesis of alpha-ribazole-5'-phosphate from
CC nicotinate mononucleotide (NAMN) and 5,6-dimethylbenzimidazole (DMB).
CC {ECO:0000256|ARBA:ARBA00002197, ECO:0000256|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:0000256|ARBA:ARBA00001058, ECO:0000256|HAMAP-
CC Rule:MF_00230};
CC -!- PATHWAY: Nucleoside biosynthesis; alpha-ribazole biosynthesis; alpha-
CC ribazole from 5,6-dimethylbenzimidazole: step 1/2.
