2VXO - PubMed Abstract: 
Guanine monophosphate (GMP) synthetase is a bifunctional two-domain enzyme. The N-terminal glutaminase domain generates ammonia from glutamine and the C-terminal synthetase domain aminates xanthine monophosphate (XMP) to form GMP. Mammalian GMP synthetases (GMPSs) contain a 130-residue-long insert in the synthetase domain in comparison to bacterial proteins ...
