Acetylome and succinylome of Corynebacterium glutamicum

Project description:Profiles of two major acyl-modifications, lysine acetylation and succinylation, under L-glutamate-producting and non-producing conditions in Corynebacterium glutamicum, which is industrially utilized for amino acid fermentation, was analyzed. During glutamate overproduction induced by Tween 40, global lysine acetylation was decreased, while lysine succinylation was increased. A label-free semi-quantitative proteomic analysis identified 591 acetylated proteins with 1,509 unique acetylation sites and 297 succinylated proteins with 790 unique succinylation sites. Lysine acetylation and succinylation targeted most enzymes in the central carbon metabolic pathways that are directly related to glutamate production, including the 2-oxoglutarate dehydrogenase complex (ODHC), a key enzyme for glutamate overproduction.

Ciprofloxacin triggers L-glutamate production by Corynebacterium glutamicum

Project description:Ciprofloxacin, an inhibitor of bacterial gyrase and topoisomerase IV, was shown to inhibit growth of C. glutamicum with concomitant excretion of L-glutamate. C. glutamicum strains overproducing L-lysine, L-arginine, L-ornithine, and putrescine, respectively, produced L-glutamate instead of the desired amino acid when exposed to ciprofloxacin. Even in the absence of the putative L-glutamate exporter gene yggB, ciprofloxacin effectively triggered L-glutamate production. When C. glutamicum wild type was cultivated under nitrogen-limiting conditions, 2-oxoglutarate rather than L-glutamate was produced as consequence of exposure to ciprofloxacin. Transcriptome analysis revealed that ciprofloxacin increased RNA levels of genes involved in DNA synthesis, repair and modification. Enzyme assays showed that 2-oxoglutarate dehydrogenase activity was decreased due to ciprofloxacin addition. Here, it was shown for the first time that production of L-glutamate by C. glutamicum may be triggered by an inhibitor of DNA synthesis and L-glutamate titers of up to 37 ± 1 mM and a substrate specific L-glutamate yield of 0.13 g/g were reached.
