Organism
Buchnera aphidicola subsp. Acyrthosiphon pisum (strain APS) (Acyrthosiphon pisum symbiotic bacterium)
Status
Reviewed-Annotation score: -Protein inferred from homologyi

Functioni

Catalyzes the synthesis of beta-nicotinate D-ribonucleotide from nicotinate and 5-phospho-D-ribose 1-phosphate at the expense of ATP.UniRule annotation

Catalytic activityi

Nicotinate + 5-phospho-alpha-D-ribose 1-diphosphate + ATP + H2O = beta-nicotinate D-ribonucleotide + diphosphate + ADP + phosphate.UniRule annotation
