About This Section
| Entrez Gene summary for HPRT1: The protein encoded by this gene is a transferase, which catalyzes conversion of hypoxanthine to inosine monophosphateand guanine to guanosine monophosphate via transfer of the 5-phosphoribosyl group from 5-phosphoribosyl1-pyrophosphate. This enzyme plays a central role in the generation of purine nucleotides through the purine salvagepathway. Mutations in this gene result in Lesch-Nyhan syndrome or gout.(provided by RefSeq, Jun 2009) UniProtKB/Swiss-Prot: HPRT_HUMAN, P00492Function: Converts guanine to guanosine monophosphate, and hypoxanthine to inosine monophosphate. Transfers the5-phosphoribosyl group from 5-phosphoribosylpyrophosphate onto the purine. Plays a central role in the generation ofpurine nucleotides through the purine salvage pathway Gene Wiki entry for HPRT1 (Hypoxanthine-guanine phosphoribosyltransferase)
