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 large chain (carB), Carbamoyl-phosphate synthase small chain (carA)
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.
Proteins known to be involved in the 3 steps of the subpathway in this organism are:
  1. Carbamoyl-phosphate synthase large chain (carB), Carbamoyl-phosphate synthase small chain (carA)
  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.
