Chemical reaction catalyzed by the inosine monophosphate dehydrogenase (IMPDH) enzyme. IMPDH functions in de novo guanine nucleotide synthesis by converting inosine 5′-monophosphate (IMP) to xanthosine 5′-monophosphate (XMP) with the concomitant reduction of nicotinamide adenine dinucleotide (NAD+) (Hedstrom 1999).
