Methanohalobium evestigatum (strain DSM 3721 / OCM 161 / Z-7303)
Status
Reviewed-Annotation score: Annotation score: 3 out of 5-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

Pathway:iIMP 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.
