GMP synthase (EC 6.3.4.1 xanthosine-5′-phosphate—ammonia ligase guanylate synthetase XMP aminase xanthosine 5′-monophosphate aminase) is an enzyme with system name xanthosine-5′-phosphate:ammonia ligase (AMP-forming). This enzyme catalyses the following chemical reaction ATP + XMP + NH3 AMP + diphosphate + GMP
