The crystal structure of GMP synthetase serves as a prototype for two, families of metabolic enzymes. The Class I glutamine amidotransferase, domain of GMP synthetase is found in related enzymes of the purine, pyrimidine, tryptophan, arginine, histidine and folic acid biosynthetic, pathways. This domain includes a conserved Cys-His-Glu triad and is, representative of a new family of enzymes that use a catalytic triad for, enzymatic hydrolysis. The structure and conserved sequence fingerprint of, the nucleotide-binding site in a second domain of GMP synthetase are, common to a family of ATP pyrophosphatases, including NAD synthetase, asparagine synthetase and argininosuccinate synthetase.
