Xanthosine monophosphate (xanthylate) is an intermediate in
purine metabolism.
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.
It is abbreviated XMP.

Xanthosine is a nucleoside derived from xanthine and ribose. It is the biosynthetic precursor to 7-methylxanthosine by the action of 7-methylxanthosine synthase. 7-Methylxanthosine in turn is the precursor to theobromine (active alkaloid in cho ...
