TranscriptomicsExploring the role of sigma factor gene expression on production by Corynebacterium glutamicum: sigma factor H and FMN as example
Bacteria are known to cope with environmental changes by using alternative sigma factors binding to RNA polymerase core enzyme. Sigma factor is one of the targets to modify transcription regulation in bacteria and to influence production capacities. In this study, the effect of overexpressing all an...

TranscriptomicsIdentification of two mutations increasing the methanol tolerance of Corynebacterium glutamicum
Background: Methanol is present in most ecosystems and may also occur in industrial applications, e.g. as an impurity of carbon sources such as technical glycerol. Methanol often inhibits growth of bacteria, thus, methanol tolerance may limit fermentative production processes. Results: The methano...

TranscriptomicsControl of heme homeostasis in Corynebacterium glutamicum by the two-component system HrrSA
The response regulator HrrA belonging to the HrrSA two-component system (previously named CgtSR11) is known to be repressed by the global iron-dependent regulator DtxR in Corynebacterium glutamicum. Sequence analysis indicated an involvement of the HrrSA system in heme-dependent gene expression. Gro...

TranscriptomicsEngineering Corynebacterium glutamicum for fast production of lysine and pipecolic acid
The Gram-positive soil bacterium Corynebacterium glutamicum is widely used in industrial fermentative processes for the production of amino acids. The world production of L-lysine has surpassed 2 million tons per year. Glucose is taken up into the C. glutamicum cell by the phosphotransferase system ...

TranscriptomicsInfluence of oxygen limitation, absence of the cytochrome bc1 complex and low pH on global gene expression in Gluconobacter oxydans 621H using DNA microarray technology
The genome-wide transcriptional responses of the strictly aerobic -proteobacterium Gluconobacter oxydans 621H to oxygen limitation, to the absence of the cytochrome bc1 complex, and to low pH were studied using DNA microarray analyses. Oxygen limitation caused expression changes of 486 genes, repres...

TranscriptomicsL-Glutamine metabolism and its regulation in C. glutamicum
Corynebacterium glutamicum, a gram-positive soil bacterium used for the industrial production of amino acids such as L-glutamate and L-lysine, is able to use a number of different nitrogen sources, such as ammonium, urea, or creatinine. In this communication, we show that L-glutamine serves as an ex...

TranscriptomicsThe Two-component Signal Transduction System CopRS of Corynebacterium glutamicum is Required for Adaptation to Copper-excess Stress
Copper is an essential cofactor for many enzymes but at high concentrations it is toxic for the cell. Copper ion concentrations ≥50 µM inhibited growth of Corynebacterium glutamicum. The transcriptional response to 20 µM Cu2+ was studied using DNA microarrays and revealed 26 genes that showed a ≥3-f...
