(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 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) In an evolutionary experiment on high hemin concentrations, a frameshift mutation in the ChrS gene was figured out to be striking in survival at high hemin concentrations (Ala245fs). Apart from high upregulation of heme exporter hrtB, microarrays should reveal further different controlled genes compared to the WT.

(Submitter supplied) We evaluated how HrrA binding in response to 4 µM heme as initial stimulus. Analysis was performed prior to the addition of heme (T0) and 0.5, 2, 4, 9, and 24 h after the heme pulse (in medium containing no other iron source).

(Submitter supplied) We evaluated how HrrA binding (found by ChAP-Seq) impacts the expression of individual target genes, by analyzing the transcriptome of the C. glutamicum wild type strain (ATCC 13032) as well as a ∆hrrA mutant. RNA-Seq analysis was performed prior to the addition of heme (T0) and 0.5 and 4 h after the heme pulse (in medium containing no other iron source).

(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) <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) DNA microarray experiments with phenylpropanoid pulses were performed in order to get hints on expression of relevant genes or gene clusters activated in presence of phenylpropanoid compounds. We determined the relative mRNA-levels of wild-type cells confronted with phenylpropanoids and unpulsed cells. A pulsing time of 30 minutes was sufficient to find regulation of gene expression in response to the phenylpropanoid amount of 5 mM (final concentration) added. 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...
