What is it about?
Feedback inhibition of the N-acetylglutamate kinase activity was shown both in C. glutamicum and in recombinant E. coli argB auxotrophic strains. Extracts of E. coli cells carrying cloned corynebacterial DNA display an ornithine acetyltransferase activity (encoded by argJ), which alleviates the acetylornithinase (encoded by argE) deficiency.

Why is it important?
This study provides a valuable information on arginine biosynthesis and regulation of corresponding genes in Corynebacterium glutamicum, a bacterium of industrial importance for production of L-amino acids.
Perspectives
Recent investigations indicate that L-arginine significantly improves the quality of cosmetic products and contributes to better composition of food additives.
