Gene

arg5

Organism
Schizosaccharomyces pombe (strain 972 / ATCC 24843) (Fission yeast)
Status
Reviewed-Annotation score: Annotation score: 3 out of 5-Protein inferred from homologyi

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 large chain (arg4), Carbamoyl-phosphate synthase arginine-specific small chain (arg5)
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.
