dc.description.abstract | The gene whcE of Corynebacterium glutamicum plays a positive role in oxidative stress responses and the WhcE protein interacts with SpiE. By utilizing 2D-PAGE analysis, we identified the otsB gene to be under the control of whcE. The transcription of otsB, encoding trehalose 6-phosphatase, was stimulated by oxidative stress, and whcE and spiE were involved in diamide-mediated transcriptional stimulation. The Delta otsB strain was created and found to be sensitive to the thiol-specific oxidant diamide, suggesting a role of the gene in stress responses. Genes located upstream of otsB, such as NCgl2534 and otsA, formed an operon and purified WhcE was able to bind to the promoter region of the operon (P-NCgl2534), but the binding was only possible in the presence of the oxidant diamide. In addition, the transcriptional activation of P-NCgl2534 by WhcE was demonstrated in in vivo assays and the transcription was stimulated in cells exposed to the oxidant diamide. These findings indicate that WhcE is a transcriptional activator, and otsB, which is involved in trehalose biosynthesis, has a role in oxidative stress responses in C. glutamicum. | - |
