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

Pathwayi: CTP biosynthesis via de novo pathway

This protein is involved in step 2 of the subpathway that synthesizes CTP from UDP.UniRule annotation
Proteins known to be involved in the 2 steps of the subpathway in this organism are:
  1. no protein annotated in this organism
  2. CTP synthase (pyrG)

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
