Protein

Acetylornithine aminotransferase

Gene

argD

Organism
Synechocystis sp. (strain PCC 6803 / Kazusa)
Status
Reviewed-Annotation score: Annotation score: 3 out of 5-Protein inferred from homologyi

Functioni

Miscellaneous

May also have succinyldiaminopimelate aminotransferase activity, thus carrying out the corresponding step in lysine biosynthesis.UniRule annotation

Catalytic activityi

N2-acetyl-L-ornithine + 2-oxoglutarate = N-acetyl-L-glutamate 5-semialdehyde + L-glutamate.UniRule annotation

Cofactori

pyridoxal 5'-phosphateUniRule annotationNote: Binds 1 pyridoxal phosphate per subunit.UniRule annotation

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 annotation
Proteins known to be involved in the 4 steps of the subpathway in this organism are:
  1. Arginine biosynthesis bifunctional protein ArgJ (argJ)
  2. Acetylglutamate kinase (argB)
  3. N-acetyl-gamma-glutamyl-phosphate reductase (argC)
  4. Acetylornithine 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.
