Function
function
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.
Catalytic activity
- XMP + diphosphate = xanthine + 5-phospho-alpha-D-ribose 1-diphosphate
Pathway
Purine metabolism; XMP biosynthesis via salvage pathway; XMP from xanthine: step 1/1.
