    Functioni

    Converts the preformed base xanthine, a product of nucleic acid breakdown, to xanthosine 5'-monophosphate (XMP), so it can be reused for RNA or DNA synthesis.UniRule annotation

    Catalytic activityi

    XMP + diphosphate = 5-phospho-alpha-D-ribose 1-diphosphate + xanthine.UniRule annotation
