Xanthosine monophosphate (xanthylate) is an intermediate in
purine metabolism
Purine metabolism refers to the metabolic pathways to synthesize and break down purines that are present in many organisms.
Biosynthesis
Purines are biologically synthesized as nucleotides and in particular as ribotides, i.e. bases attached to r ...

Guanosine monophosphate synthetase, () also known as GMPS is an enzyme that converts xanthosine monophosphate to guanosine monophosphate.
In the de novo synthesis of purine nucleotides, IMP is the branch point metabolite at which point the pathw ...

Xanthosine
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 ...
