inactivation of argJ does not cause arginine auxotrophy or marked growth defects
malfunction
enzyme inhibitor pranlukast (PRK) treatment remarkably abates the survival of free as well as macrophage-internalized Mtb, and shows enhanced efficacy in combination with standard-of-care drugs. Notably, PRK also reduces the 5-lipoxygenase (5-LO) signaling in the infected macrophages, thereby surmounting an enhanced response against intracellular pathogen. Further, treatment with PRK alone or with rifampicin leads to significant decrease in Mycobacterium tuberculosis burden and tubercular granulomas in Mtb-infected mice lungs. PRK-mediated killing of Mycobacterium tuberculosis is rescued upon arginine supplementation

overexpression of a OTase in Corynebacterium crenatum leads to an improvement of L-Arginine production
metabolism
ArgJ plays a vital role in the L-citrulline biosynthesis. The enzyme exerts feedback inhibition on N-acetylglutamate synthase, pathway overview
metabolism
enzyme ArgJ strongly influences the production of L-ornithine in Corynebacterium glutamicum. L-Ornithine is a nonessential amino acid that is effective in treating liver diseases and in liver protection and wound healing and is capable of strengthening the heart. L-Ornithine is also an important constituent of the urea cycle. As the precursor of L-citrulline and L-arginine, L-ornithine is biosynthesized by the cyclic pathway in five steps through a series of acetylated intermediates in Corynebacterium glutamicum. In the ornithine biosynthetic pathway of Corynebacterium glutamicum, L-ornithine and N-acetylglutamate are produced by ornithine acetyltransferase (OATase, ArgJ) using acetylornithine and glutamate as substrates. Corynebacterium glutamicum possesses a monofunctional ArgJ protein that only exhibits OAT activity, lacks N-acetylglutamate synthetase activity, and only catalyses the fifth step of the L-citrulline biosynthesis pathway, in which glutamate is acetylated by the N-acetylglutamate synthase Cg3035. Inactivating ArgR decreases the feedback repression of L-ornithine synthesis and enhanced L-ornithine production in Corynebacterium glutamicum. Significant increase in L-ornithine concentration under homologous argJ overexpression
metabolism
the enzyme is involved in the arginine biosynthetic pathway
metabolism
the L-ornithine biosynthetic pathway is cyclic due to L-ornithine acetyltransferase (OATase), which catalyzes the conversion of N-acetyl-L-ornithine and L-glutamate to L-ornithine and N-acetyl-Lglutamate (NAG). NAG kinase (NAGK, encoded by argB, EC 2.7.2.8) then phosphorylates NAG in the second step of the pathway. In addition to OATase and NAGK, argC-encoded N-acetyl-L-glutamate 5-semialdehyde dehydrogenase, and argD-encoded N-acetyl-L-ornithine aminotransferase are critical for the conversion of L-glutamate to L-ornithine. These four genes are generally involved in one of the L-arginine synthesis clusters, named argCJBD in Corynebacterium strains
