Allosteric1
  • Purine synthesis is regulated by the allosteric inhibition of IMP formation by the adenine or guanine nucleotides. (wikipedia.org)
Purine1
  • Xanthylic 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).
