Functioni

Catalytic activityi

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

Pathwayi: L-arginine biosynthesis

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

Pathwayi: UMP biosynthesis via de novo pathway

This protein is involved in step 1 of the subpathway that synthesizes (S)-dihydroorotate from bicarbonate.UniRule annotation
Proteins known to be involved in the 3 steps of the subpathway in this organism are:
  1. Carbamoyl-phosphate synthase small chain (carA), Carbamoyl-phosphate synthase large chain (carB)
  2. Aspartate carbamoyltransferase (pyrB)
  3. Dihydroorotase (pyrC)
This subpathway is part of the pathway UMP biosynthesis via de novo pathway, which is itself part of Pyrimidine metabolism.

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.UniRule annotation
