Gene

gpt

Organism
Roseivivax marinus
Status
Unreviewed-Annotation score: -Protein inferred from homologyi

Functioni

Acts on guanine, xanthine and to a lesser extent hypoxanthine.UniRule annotationSAAS annotation

Caution

The sequence shown here is derived from an EMBL/GenBank/DDBJ whole genome shotgun (WGS) entry which is preliminary data.Imported

Catalytic activityi

XMP + diphosphate = 5-phospho-alpha-D-ribose 1-diphosphate + xanthine.UniRule annotationSAAS annotation

Cofactori

Mg2+UniRule annotationNote: Binds 1 Mg2+ ion per subunit.UniRule annotation

Pathwayi: XMP biosynthesis via salvage pathway

This protein is involved in step 1 of the subpathway that synthesizes XMP from xanthine.UniRule annotationSAAS annotation
Proteins known to be involved in this subpathway in this organism are:
  1. Xanthine phosphoribosyltransferase (gpt)
This subpathway is part of the pathway XMP biosynthesis via salvage pathway, which is itself part of Purine metabolism.
