(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) The extracytoplasmic function sigma factor SigH is responsible for heat and oxidative stress response in a biotechnologically -important bacterium Corynebacterium glutamicum. Due to the hierarchical nature of the regulatory network, it has not been possible to fully determine the SigH regulon by previous transcriptome analyses. Here, we determined the direct genome-wide targets of SigH were determined by ChIP-chip analysis using a deletion mutant of rshA, encoding an anti-sigma factor of SigH. more...

(Submitter supplied) 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 PTS which can be replaced and/or enhanced by a permease and a glucokinase. Heterologous expression of the gene for the high-affinity glucose permease from Streptomyces coelicolor and of the Bacillus subitilis glucokinase gene fully compensated for the absence of the PTS in hpr strains and strains grew as fast with glucose as C. 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) In the analysis of a carbohydrate metabolite pathway, we found that a mutant strain of Corynebacterium glutamicum deficient in pfkB1, which encodes fructose-1-phosphate kinase, showed interesting characteristics. After aerobically cultivated with fructose as a carbon source, this mutant consumed glucose and produced lactate more than 2-fold as compared with the wild-type under conditions of oxygen deprivation. more...

(Submitter supplied) Cell proliferation is achieved by numerous enzyme reactions. Temperature governs the activity of each enzyme, which overall determines the optimal growth temperature. Synthesizing useful chemicals and fuels utilizes only part of the metabolic pathways, especially the central metabolic pathways such as glycolysis and TCA cycle to metabolize glucose. However, the optimal temperature for the activity of the central metabolic pathways is inconclusive whether it is correlated with the optimal temperature for cell proliferation. more...
