Figure 1From: A new class of IMP dehydrogenase with a role in self-resistance of mycophenolic acid producing fungiRole of IMPDH and MPA in GMP biosynthesis. MPA inhibits IMPDH. MPA: Mycophenolic acid. R: ribose 5'-monophosphate. IMP: inosine-5'-monophosphate, XMP: xanthosine-5'-monophosphate, guanosine-5'-monophosphate. GMP: Guanosine monophosphate. IMPDH: IMP dehydrogenase.Back to article page
