Gene

pncB

Organism
Salmonella typhimurium (strain LT2 / SGSC1412 / ATCC 700720)
Status
Reviewed-Annotation score: -Experimental evidence at protein leveli

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

Pathwayi: NAD(+) biosynthesis

This protein is involved in step 1 of the subpathway that synthesizes nicotinate D-ribonucleotide from nicotinate.UniRule annotation
Proteins known to be involved in this subpathway in this organism are:
  1. Nicotinate phosphoribosyltransferase (pncB)
This subpathway is part of the pathway NAD(+) biosynthesis, which is itself part of Cofactor biosynthesis.
