Comments [?]

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	Reaction=diphosphate + XMP = 5-phospho-alpha-D-ribose 1-diphosphate + xanthine; Xref=Rhea:RHEA:10800, ChEBI:CHEBI:17712, ChEBI:CHEBI:33019, ChEBI:CHEBI:57464, ChEBI:CHEBI:58017; EC=2.4.2.22;
PATHWAY	Purine metabolism; XMP biosynthesis via salvage pathway; XMP from xanthine: step 1/1.
SUBUNIT	Homodimer.
SUBCELLULAR LOCATION	Cytoplasm.
SIMILARITY	Belongs to the purine/pyrimidine phosphoribosyltransferase family. Xpt subfamily.
