(Submitter supplied) DNA affinity chromatography with the promoter region of the Corynebacterium glutamicum pck gene, encoding phosphoenolpyruvate carboxykinase (PEPCk), led to the isolation of four transcriptional regulators, i.e., RamA, GntR1, GntR2 and IolR. Determination of the PEPCk activity of the deletion mutants ΔramA, ΔgntR1ΔgntR2, and ΔiolR indicated that RamA represses pck during growth on glucose about twofold, whereas GntR1, GntR2, and IolR activate pck expression about twofold, irrespective whether glucose or acetate served as carbon source. more...

(Submitter supplied) The transcriptional regulator GntR1 downregultates the genes for gluconate catabolism and pentose phosphate pathway in Corynebacterium glutamicum. Gluconate lowers the DNA binding affinity of GntR1, which is probably the mechanism of gluconate-dependent induction of these genes. In addition, GntR1 positively regulates the ptsG, a gene encoding for a major glucose transporter, and the pck, a gene encoding phosphoenolpyruvate carboxykinase. more...

(Submitter supplied) <Background> The pstSCAB operon of Corynebacterium glutamicum, which encodes an ABC transport system for uptake of phosphate (Pi), is induced during the P i starvation response. The two-component regulatory system PhoRS is involved in this response, but partial Pi starvation induction of pstSCAB in a ∆phoRS mutant indicated the involvement of additional regulator(s). Regulation of pstSCAB also involves the global transcriptional regulator GlxR. more...

(Submitter supplied) We recently showed that the two-component system (TCS) HrrSA plays a central role in the control of heme homeostasis in the Gram-positive soil bacterium Corynebacterium glutamicum. Here, we characterized the function of another TCS of this organism, ChrSA, which exhibits significant sequence similarity to HrrSA, and provide evidence for cross-regulation of the two systems. In this study ChrSA was shown to be crucial for heme resistance of C. more...

(Submitter supplied) The order Rhizobiales contains numerous agriculturally, biotechnologically, and medically important bacteria including the rhizobia, Agrobacterium, Brucella, and Methylobacterium, among others. These organisms tend to be metabolically versatile, but there has been relatively little investigation into the regulation of their central carbon metabolic pathways. Here, RNA-seq and promoter fusion data are presented to show that the PckR protein is a key regulator of central carbon metabolism in Sinorhizobium meliloti; during growth with gluconeogenic substrates, PckR represses expression of the complete Entner-Doudoroff glycolytic pathway and induces expression of the pckA and fbaB gluconeogenic genes. more...

(Submitter supplied) Corynebacterium glutamicum GlxR is a homolog of the cAMP receptor protein. Although over 200 GlxR binding sites in the C. glutamicum genome are predicted in silico, studies on the GlxR physiological function have been hindered by the severe growth defects of a glxR mutant. This study comprehensively identified the GlxR regulon by chromatin immunoprecipitation in conjunction with microarray (ChIP-chip) analyses. more...

(Submitter supplied) Methanol is considered as an interesting carbon source in biobased microbial production processes. As Corynebacterium glutamicum is an important host in industrial biotechnology, in particular for amino acid production, we performed studies on the response of this organism to methanol. C. glutamicum wild type was able to convert 13C-labeled methanol to 13CO2. Analysis of global gene expression in the presence of methanol revealed several genes of ethanol catabolism to be up-regulated, indicating that some of the corresponding enzymes are involved in methanol oxidation. more...

(Submitter supplied) 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-fold increased mRNA level, including cg3280-cg3289. Several genes in this genomic region code for proteins presumably involved in the adaption to copper-induced stress, e. more...

(Submitter supplied) 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. Growth experiments revealed that the non-pathogenic soil bacterium C. glutamicum is able to use hemin or hemoglobin as sole iron source. more...

(Submitter supplied) The development of new drugs against tuberculosis and diphtheria is focused on disrupting the biogenesis of the cell wall, the unique architecture of which confers resistance against current therapies. The enzymatic pathways involved in the synthesis of the cell wall by these pathogens are well understood but the underlying regulatory mechanisms are largely unknown. Here, we characterize IpsA, a LacI-type transcriptional regulator conserved among Mycobacteria and Corynebacteria that plays a role in the regulation of cell wall biogenesis. more...
