Kineticsⁱ

Pathwayⁱ: L-arginine biosynthesis

This protein is involved in step 4 of the subpathway that synthesizes N(2)-acetyl-L-ornithine from L-glutamate.UniRule annotation1 Publication
Proteins known to be involved in the 4 steps of the subpathway in this organism are:

Amino-acid acetyltransferase (argA)
Acetylglutamate kinase (argB)
N-acetyl-gamma-glutamyl-phosphate reductase (argC)
Acetylornithine/succinyldiaminopimelate aminotransferase (argD)

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 N(2)-acetyl-L-ornithine from L-glutamate, the pathway L-arginine biosynthesis and in Amino-acid biosynthesis.

Pathwayⁱ: L-lysine biosynthesis via DAP pathway

This protein is involved in step 2 of the subpathway that synthesizes LL-2,6-diaminopimelate from (S)-tetrahydrodipicolinate (succinylase route).UniRule annotation1 Publication
Proteins known to be involved in the 3 steps of the subpathway in this organism are:

2,3,4,5-tetrahydropyridine-2,6-dicarboxylate N-succinyltransferase (dapD)
Acetylornithine/succinyldiaminopimelate aminotransferase (argD)
Succinyl-diaminopimelate desuccinylase (dapE)

This subpathway is part of the pathway L-lysine biosynthesis via DAP pathway, which is itself part of Amino-acid biosynthesis.
