Metabolite Identification
Common NameXanthylic acid
DescriptionXanthylic acid is an important metabolic intermediate in the Purine Metabolism, and is a product or substrate of the enzymes Inosine monophosphate dehydrogenase (EC 1.1.1.205), Hypoxanthine phosphoribosyltransferase (EC 2.4.2.8), Xanthine phosphoribosyltransferase (EC 2.4.2.22), 5'-Ribonucleotide phosphohydrolase (EC 3.1.3.5), Ap4A hydrolase (EC 3.6.1.17), Nucleoside-triphosphate diphosphatase (EC 3.6.1.19), Phosphoribosylamine-glycine ligase (EC 6.3.4.1), and glutamine amidotransferase (EC 6.3.5.2). (KEGG) Xanthylic acid can also be used in quantitative measurements of the Inosine monophosphate dehydrogenase enzyme activities in purine metabolism. This measurement is important for optimal thiopurine therapy for children with acute lymphoblastic leukaemia (ALL). (PMID: 16725387 ).

6. Inosine triphosphate pyrophosphatase
General function:
Involved in hydrolase activity
Specific function:
