CTP synthase

Gene

pyrG

Organism
Brucella melitensis biotype 1 (strain 16M / ATCC 23456 / NCTC 10094)
Status
Reviewed - Annotation score: 3 out of 5- Protein inferred from homologyi

Functioni

Catalyzes the ATP-dependent amination of UTP to CTP with either L-glutamine or ammonia as the source of nitrogen.UniRule annotation

Catalytic activityi

ATP + UTP + L-glutamine = ADP + phosphate + CTP + L-glutamate.UniRule annotation

Enzyme regulationi

Allosterically activated by GTP, when glutamine is the substrate. Inhibited by CTP.UniRule annotation
