UniProtKB - P00492 (HPRT_HUMAN)

Protein

Hypoxanthine-guanine phosphoribosyltransferase

Gene

HPRT1

Organism
Homo sapiens (Human)
Status
Reviewed-Annotation score: -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.

Catalytic activityi

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

Cofactori

Mg2+Note: Binds 2 magnesium ions per subunit. The magnesium ions are essentially bound to the substrate and have few direct interactions with the protein.

    Pathwayi: IMP biosynthesis via salvage pathway

    This protein is involved in step 1 of the subpathway that synthesizes IMP from hypoxanthine.
    Proteins known to be involved in this subpathway in this organism are:
    1. Hypoxanthine-guanine phosphoribosyltransferase (HPRT1), Hypoxanthine phosphoribosyltransferase, Hypoxanthine phosphoribosyltransferase (hprT), Hypoxanthine phosphoribosyltransferase (HPRT1)
    This subpathway is part of the pathway IMP biosynthesis via salvage pathway, which is itself part of Purine metabolism.
    View all proteins of this organism that are known to be involved in the subpathway that synthesizes IMP from hypoxanthine, the pathway IMP biosynthesis via salvage pathway and in Purine metabolism.
