Gene

upp

Organism
Pseudomonas mendocina (strain ymp)
Status
Reviewed-Annotation score: -Protein inferred from homologyi

Functioni

Catalyzes the conversion of uracil and 5-phospho-alpha-D-ribose 1-diphosphate (PRPP) to UMP and diphosphate.UniRule annotation

Catalytic activityi

UMP + diphosphate = uracil + 5-phospho-alpha-D-ribose 1-diphosphate.UniRule annotation

Cofactori

Mg2+UniRule annotationNote: Binds 1 Mg2+ ion per subunit. The magnesium is bound as Mg-PRPP.UniRule annotation

Activity regulationi

Allosterically activated by GTP.UniRule annotation

Pathwayi: UMP biosynthesis via salvage pathway

This protein is involved in step 1 of the subpathway that synthesizes UMP from uracil.UniRule annotation
Proteins known to be involved in this subpathway in this organism are:
  1. Uracil phosphoribosyltransferase (upp)
This subpathway is part of the pathway UMP biosynthesis via salvage pathway, which is itself part of Pyrimidine metabolism.
