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. HAMAP-Rule MF_01227

Catalytic activity

ATP + UTP + L-glutamine = ADP + phosphate + CTP + L-glutamate. HAMAP-Rule MF_01227

Enzyme regulation

Allosterically activated by GTP, when glutamine is the substrate. Inhibited by CTP By similarity. HAMAP-Rule MF_01227

Pathway

Pyrimidine metabolism; CTP biosynthesis via de novo pathway; CTP from UDP: step 2/2. HAMAP-Rule MF_01227

Subunit structure

Homotetramer By similarity. HAMAP-Rule MF_01227

Sequence similarities

Belongs to the CTP synthase family.

Contains 1 glutamine amidotransferase type-1 domain.
