| + | [https://www.uniprot.org/uniprot/HGPRT_MYCTU HGPRT_MYCTU] Purine salvage pathway enzyme that catalyzes the transfer of the ribosyl-5-phosphate group from 5-phospho-alpha-D-ribose 1-diphosphate (PRPP) to the N9 position of the 6-oxopurines hypoxanthine and guanine to form the corresponding ribonucleotides IMP (inosine 5'-monophosphate) and GMP (guanosine 5'-monophosphate), with the release of PPi (PubMed:19362594, PubMed:25915781). Thus, specifically recycles hypoxanthine and guanine imported from the external medium, and converts them to IMP and GMP, respectively. Cannot use xanthine as substrate (PubMed:19362594).<ref>PMID:19362594</ref> <ref>PMID:25915781</ref> | ||
