CC   -!- FUNCTION: Converts the preformed base xanthine, a product of nucleic
CC       acid breakdown, to xanthosine 5'-monophosphate (XMP), so it can be
CC       reused for RNA or DNA synthesis. {ECO:0000255|HAMAP-Rule:MF_01184}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=diphosphate + XMP = 5-phospho-alpha-D-ribose 1-diphosphate +
CC         xanthine; Xref=Rhea:RHEA:10800, ChEBI:CHEBI:17712, ChEBI:CHEBI:33019,
CC         ChEBI:CHEBI:57464, ChEBI:CHEBI:58017; EC=2.4.2.22;
CC         Evidence={ECO:0000255|HAMAP-Rule:MF_01184};
CC   -!- PATHWAY: Purine metabolism; XMP biosynthesis via salvage pathway; XMP
CC       from xanthine: step 1/1. {ECO:0000255|HAMAP-Rule:MF_01184}.
CC   -!- SUBUNIT: Homodimer. {ECO:0000255|HAMAP-Rule:MF_01184}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_01184}.
CC   -!- SIMILARITY: Belongs to the purine/pyrimidine phosphoribosyltransferase
CC       family. Xpt subfamily. {ECO:0000255|HAMAP-Rule:MF_01184}.
