General annotation (Comments)

Function	Catalyzes the ATP-dependent amination of UTP to CTP with either L-glutamine or ammonia as the source of nitrogen By similarity.
Catalytic activity	ATP + UTP + NH3 = ADP + phosphate + CTP. HAMAP MF_01227
Enzyme regulation	Allosterically activated by GTP, when glutamine is the substrate. Inhibited by CTP By similarity.
Pathway	Pyrimidine metabolism; CTP biosynthesis via de novo pathway; CTP from UDP: step 2/2. HAMAP MF_01227
Subunit structure	Homotetramer By similarity.
Sequence similarities	Belongs to the CTP synthase family. Contains 1 glutamine amidotransferase type-1 domain.
