IMPDH controls the gateway to guanine nucleotides, making it an “enzyme of consequence” for virtually every organism. Humans and other mammals have two IMPDH genes, encoding hIMPDH1 and hIMPDH2. The IMPDH-catalyzed conversion of IMP to XMP is the first committed and rate-limiting step in guanine nucleotide biosynthesis. XMP is subsequently converted to GMP by the action of GMP synthetase (GMPS). |

AMP deaminase (AMPD; EC 3.5.4.6) is encoded by a multigene family in mammals. The AMPD1 gene is expressed at high levels in skeletal muscle, where this enzyme is thought to play an important role in energy metabolism. AMP deaminase (AMPD; EC 3.5.4.6), an enzyme that catalyzes deamination of AMP to IMP, and the purine nucleotide cycle, of which AMPD is one component, play a central role in purine nucleotide interconversion in eukaryotic cells. |

The last two steps in the pathway are catalyzed by the bifunctional AICAR transformylase/IMP cyclohydrolase (ATIC). The transformylase domain of the enzyme first catalyzes the conversion of AICAR to formylaminoimida zole-4-carboxamide ribonucleotide (FAICAR) using the N10-formyltetrahydrofolate. Then, the cyclohydrolase domain closes the purine ring to form IMP. |
