Functioni

Catalytic activityi

2 ATP + L-glutamine + HCO3- + H2O = 2 ADP + phosphate + L-glutamate + carbamoyl phosphate.

Pathwayi: L-arginine biosynthesis

This protein is involved in step 1 of the subpathway that synthesizes carbamoyl phosphate from bicarbonate.
Proteins known to be involved in this subpathway in this organism are:
  1. Carbamoyl-phosphate synthase arginine-specific small chain (carA), Carbamoyl-phosphate synthase arginine-specific large chain (carB)
This subpathway is part of the pathway L-arginine biosynthesis, which is itself part of Amino-acid biosynthesis.

Interactioni

Subunit structurei

Composed of two chains; the small (or glutamine) chain promotes the hydrolysis of glutamine to ammonia, which is used by the large (or ammonia) chain to synthesize carbamoyl phosphate.

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.
