XTP diphosphatase activity https://github.com/geneontology/go-ontology/issues/19078 https://github.com/geneontology/go-ontology/issues/28526 XTP pyrophosphohydrolase activity KEGG_REACTION:R02720 GO:0036222 XTPase activity While XTP is not produced by cells, deamination of purine bases can result in accumulation of such nucleotides as ITP, dITP, XTP, and dXTP. XTPase contributes to the removal of these abnormal bases from the cellular pool of nucleotide triphosphates. XTP/dITP diphosphatase Catalysis of the reaction: XTP + H2O = XMP + H+ + diphosphate.
