catalytic activity:ATP + UTP + NH(3) = ADP + phosphate + CTP.,enzyme regulation:Activated by GTP and inhibited by CTP.,function:Catalyzes the ATP-dependent amination of UTP to CTP with either L-glutamine or ammonia as the source of nitrogen.,pathway:Pyrimidine metabolism; CTP biosynthesis via de novo pathway; CTP from UDP: step 2/2.,similarity:Belongs to the CTP synthase family.,similarity:Contains 1 glutamine amidotransferase type-1 domain.,
Cytoplasm, cytosol . Mainly cytosolic but when active detected in long filamentous structures (PubMed:25223282). Co-localizes with TNK2 in the cytosolic filaments (By similarity). .
Widely expressed.
