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
