Xanthosine monophosphate

Xanthosine monophosphate (xanthylate) is an intermediate in purine metabolism.^[1] It is a ribonucleoside monophosphate. It is formed from IMP via the action of IMP dehydrogenase, and it forms GMP via the action of GMP synthase. Also, XMP can be released from XTP by enzyme deoxyribonucleoside triphosphate pyrophosphohydrolase containing (d)XTPase activity.^[2]
