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 MF_01227

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. HAMAP MF_01227

Pathway

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

Subunit structure

Homotetramer By similarity. HAMAP MF_01227

Sequence similarities

Belongs to the CTP synthase family.

Contains 1 glutamine amidotransferase type-1 domain.
