CC   -!- FUNCTION: Catalyzes the synthesis of beta-nicotinate D-ribonucleotide
CC       from nicotinate and 5-phospho-D-ribose 1-phosphate at the expense of
CC       ATP. {ECO:0000255|HAMAP-Rule:MF_00570}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=5-phospho-alpha-D-ribose 1-diphosphate + ATP + H2O +
CC         nicotinate = ADP + diphosphate + nicotinate beta-D-ribonucleotide +
CC         phosphate; Xref=Rhea:RHEA:36163, ChEBI:CHEBI:15377,
CC         ChEBI:CHEBI:30616, ChEBI:CHEBI:32544, ChEBI:CHEBI:33019,
CC         ChEBI:CHEBI:43474, ChEBI:CHEBI:57502, ChEBI:CHEBI:58017,
CC         ChEBI:CHEBI:456216; EC=6.3.4.21; Evidence={ECO:0000255|HAMAP-
CC         Rule:MF_00570};
CC   -!- PATHWAY: Cofactor biosynthesis; NAD(+) biosynthesis; nicotinate D-
CC       ribonucleotide from nicotinate: step 1/1. {ECO:0000255|HAMAP-
CC       Rule:MF_00570}.
CC   -!- PTM: Transiently phosphorylated on a His residue during the reaction
CC       cycle. Phosphorylation strongly increases the affinity for substrates
CC       and increases the rate of nicotinate D-ribonucleotide production.
CC       Dephosphorylation regenerates the low-affinity form of the enzyme,
CC       leading to product release. {ECO:0000255|HAMAP-Rule:MF_00570}.
CC   -!- SIMILARITY: Belongs to the NAPRTase family. {ECO:0000255|HAMAP-
CC       Rule:MF_00570}.
