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:0000256|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:0000256|HAMAP-Rule:MF_01184};
CC -!- PATHWAY: Purine metabolism; XMP biosynthesis via salvage pathway; XMP
CC from xanthine: step 1/1. {ECO:0000256|HAMAP-Rule:MF_01184}.
CC -!- SUBUNIT: Homodimer. {ECO:0000256|HAMAP-Rule:MF_01184}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000256|HAMAP-Rule:MF_01184}.
CC -!- SIMILARITY: Belongs to the purine/pyrimidine phosphoribosyltransferase
CC family. Xpt subfamily. {ECO:0000256|HAMAP-Rule:MF_01184}.
