Sequence statusComplete.
Protein existenceInferred from homology

General annotation (Comments)

Function

Catalyzes a salvage reaction resulting in the formation of IMP that is energically less costly than de novo synthesis By similarity. HAMAP-Rule MF_01467

Catalytic activity

IMP + diphosphate = hypoxanthine + 5-phospho-alpha-D-ribose 1-diphosphate. HAMAP-Rule MF_01467

GMP + diphosphate = guanine + 5-phospho-alpha-D-ribose 1-diphosphate. HAMAP-Rule MF_01467

Pathway

Purine metabolism; IMP biosynthesis via salvage pathway; IMP from hypoxanthine: step 1/1. HAMAP-Rule MF_01467

Subunit structure

Homodimer By similarity. HAMAP-Rule MF_01467

Subcellular location

Cytoplasm By similarity HAMAP-Rule MF_01467.

Sequence similarities

Belongs to the purine/pyrimidine phosphoribosyltransferase family. Archaeal HPRT subfamily.

Sequence caution

The sequence AAB85798.1 differs from that shown. Reason: Erroneous initiation. Translation N-terminally shortened.
