Function
function
Catalyzes the synthesis of beta-nicotinate D-ribonucleotide from nicotinate and 5-phospho-D-ribose 1-phosphate at the expense of ATP.
Catalytic activity
- nicotinate + 5-phospho-alpha-D-ribose 1-diphosphate + ATP + H2O = nicotinate beta-D-ribonucleotide + ADP + phosphate + diphosphate
Pathway
Cofactor biosynthesis; NAD+ biosynthesis; nicotinate D-ribonucleotide from nicotinate: step 1/1.

Features
Showing features for modified residue.
Type | ID | Position(s) | Description | ||
---|---|---|---|---|---|
Modified residue | 213 | Phosphohistidine; by autocatalysis | |||
Post-translational modification
Transiently phosphorylated on a His residue during the reaction cycle. Phosphorylation strongly increases the affinity for substrates and increases the rate of nicotinate D-ribonucleotide production. Dephosphorylation regenerates the low-affinity form of the enzyme, leading to product release.
