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:0000256|HAMAP-Rule:MF_00570, ECO:0000256|RuleBase:RU003838}.
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:0000256|HAMAP-
CC Rule:MF_00570, ECO:0000256|RuleBase:RU003838};
CC -!- PATHWAY: Cofactor biosynthesis; NAD(+) biosynthesis; nicotinate D-
CC ribonucleotide from nicotinate: step 1/1.
CC {ECO:0000256|ARBA:ARBA00004952, ECO:0000256|HAMAP-Rule:MF_00570,
CC ECO:0000256|RuleBase:RU003838}.
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:0000256|HAMAP-Rule:MF_00570,
CC ECO:0000256|RuleBase:RU003838}.
CC -!- SIMILARITY: Belongs to the NAPRTase family.
CC {ECO:0000256|ARBA:ARBA00010897, ECO:0000256|HAMAP-Rule:MF_00570,
CC ECO:0000256|RuleBase:RU003838}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
