Protein

Ribose-phosphate pyrophosphokinase

Gene

prs

Organism
Staphylococcus aureus (strain Mu50 / ATCC 700699)
Status
Reviewed-Annotation score: -Protein inferred from homologyi

Functioni

Involved in the biosynthesis of the central metabolite phospho-alpha-D-ribosyl-1-pyrophosphate (PRPP) via the transfer of pyrophosphoryl group from ATP to 1-hydroxyl of ribose-5-phosphate (Rib-5-P).UniRule annotation

Catalytic activityi

ATP + D-ribose 5-phosphate = AMP + 5-phospho-alpha-D-ribose 1-diphosphate.UniRule annotation

Cofactori

Mg2+UniRule annotationNote: Binds 2 Mg2+ ions per subunit.UniRule annotation

Pathwayi: 5-phospho-alpha-D-ribose 1-diphosphate biosynthesis

This protein is involved in step 1 of the subpathway that synthesizes 5-phospho-alpha-D-ribose 1-diphosphate from D-ribose 5-phosphate (route I).UniRule annotation
Proteins known to be involved in this subpathway in this organism are:
  1. Ribose-phosphate pyrophosphokinase (prs)
This subpathway is part of the pathway 5-phospho-alpha-D-ribose 1-diphosphate biosynthesis, which is itself part of Metabolic intermediate biosynthesis.
View all proteins of this organism that are known to be involved in the subpathway that synthesizes 5-phospho-alpha-D-ribose 1-diphosphate from D-ribose 5-phosphate (route I), the pathway 5-phospho-alpha-D-ribose 1-diphosphate biosynthesis and in Metabolic intermediate biosynthesis.
