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

Pathway: 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)
This subpathway is part of the pathway CTP biosynthesis via de novo pathway, which is itself part of Pyrimidine metabolism.

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 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.
