    Functioni

    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.By similarity
