Protein

Ornithine carbamoyltransferase

Gene

arcB

Organism
Staphylococcus aureus (strain USA300)
Status
Unreviewed-Annotation score: Annotation score: 2 out of 5-Protein inferred from homologyi

Functioni

Reversibly catalyzes the transfer of the carbamoyl group from carbamoyl phosphate (CP) to the N(epsilon) atom of ornithine (ORN) to produce L-citrulline.SAAS annotation

Catalytic activityi

Carbamoyl phosphate + L-ornithine = phosphate + L-citrulline.UniRule annotationSAAS annotation

Pathwayi: L-arginine biosynthesis

This protein is involved in step 1 of the subpathway that synthesizes L-arginine from L-ornithine and carbamoyl phosphate.UniRule annotation
Proteins known to be involved in the 3 steps of the subpathway in this organism are:
  1. Ornithine carbamoyltransferase (arcB), Ornithine carbamoyltransferase (arcB), Ornithine carbamoyltransferase (argF)
  2. Argininosuccinate synthase (argG)
  3. Argininosuccinate lyase (argH)
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 L-arginine from L-ornithine and carbamoyl phosphate, the pathway L-arginine biosynthesis and in Amino-acid biosynthesis.
