Protein

Hypoxanthine-guanine phosphoribosyltransferase

Gene
Hprt1, Hprt
Organism
Rattus norvegicus (Rat)
Status
Reviewed - Annotation score: 5 out of 5 - Experimental evidence at protein leveli

Functioni

Converts guanine to guanosine monophosphate, and hypoxanthine to inosine monophosphate. Transfers the 5-phosphoribosyl group from 5-phosphoribosylpyrophosphate onto the purine. Plays a central role in the generation of purine nucleotides through the purine salvage pathway By similarity.

Catalytic activityi

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

Cofactori

Binds 2 magnesium ions per subunit. The magnesium ions are essentially bound to the substrate and have few direct interactions with the protein By similarity.
