Protein

Hypoxanthine/guanine phosphoribosyltransferase

Gene

hpt

Organism
Methanococcus maripaludis (strain C7 / ATCC BAA-1331)
Status
Reviewed-Annotation score: -Protein inferred from homologyi

Functioni

Catalyzes a salvage reaction resulting in the formation of IMP that is energically less costly than de novo synthesis.UniRule annotation

Catalytic activityi

IMP + diphosphate = hypoxanthine + 5-phospho-alpha-D-ribose 1-diphosphate.UniRule annotation
GMP + diphosphate = guanine + 5-phospho-alpha-D-ribose 1-diphosphate.UniRule annotation

Pathwayi: IMP biosynthesis via salvage pathway

This protein is involved in step 1 of the subpathway that synthesizes IMP from hypoxanthine.UniRule annotation
Proteins known to be involved in this subpathway in this organism are:
  1. Hypoxanthine/guanine phosphoribosyltransferase (hpt)
This subpathway is part of the pathway IMP biosynthesis via salvage pathway, which is itself part of Purine metabolism.
View all proteins of this organism that are known to be involved in the subpathway that synthesizes IMP from hypoxanthine, the pathway IMP biosynthesis via salvage pathway and in Purine metabolism.
