This family consists of the N-terminal region of the CTP synthase protein (EC:6.3.4.2). This family is found in conjunction with Pfam:PF00117 located in the C-terminal region of the protein. CTP synthase catalyses the synthesis of CTP from UTP by amination of the pyrimidine ring at the 4-position [1].	Domain
