GMP synthetase is a glutamine amidotransferase from the de novo purine biosynthetic pathway. This family is the C-terminal domain specific to the GMP synthases Swiss:P49915 EC:6.3.5.2. In prokaryotes this domain mediates dimerisation. Eukaryotic GMP synthases are monomers. This domain in eukaryotes includes several large insertions that may form globular domains.	Domain
A, B	PF02540	NAD synthase (NAD_synthase)	NAD synthase	NAD synthase (EC:6.3.5.1) is involved in the de novo synthesis of NAD and is induced by stress factors such as heat shock and glucose limitation.	Domain
