(Submitter supplied) We propose a strain engineering approach for synthesizing sedoheptulose using glucose as sole feedstock. The gene pfkA encoding 6-phosphofructokinase in Corynebacterium glutamicum was inactivated to direct the carbon flux towards pentose phosphate pathway in the cellular metabolic network. This genetic modification successfully enabled the synthesis of sedoheptulose from glucose. Additionally, we identified key enzymes responsible for product formation through transcriptome analysis, and their corresponding genes were overexpressed, resulting in a further 20% increase in sedoheptulose production.

(Submitter supplied) Efficient assimilation of renewable feedstocks is the cornerstone for achieving sustainable and economical microbial production of commodity chemicals. Unfortunately, most renewables are foreign to the cellular metabolism of classical industrial workhorses, resulting in unsatisfactory biomanufacturing performance. Here, Corynebacterium glutamicum was systematically engineered for rapid non-natural xylose metabolism and the underlying adaptations were elucidated by combining metabolic engineering, adaptive laboratory evolution and systems biology techniques. 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 assessed changes in gene expression in response to manganese availability for the human pathogen Corynebacterium diphtheriae. Total RNA was harvested from wild-type C. diphtheriae strain 1737 and an isogenic ΔmntR (dip0619) grown in semi-defined metal-limited media (mPGT) without or with 5 µM manganese chloride supplementation. Three biological replicates were prepared and five genes were assessed by real-time PCR to validate the array results: dip0124, dip0169, dip0615, dip1923, and dip2261. more...

(Submitter supplied) RNA degradation is a crucial process in bacterial cells for maintaining proper transcriptome homeostasis and coping with changing environments. A specialized ribonuclease known as RNase J (RnJ) participates in mRNA turnover in many Gram-positive bacteria; however, nothing is known about this process in Corynebacterium diphtheriae, nor is the identity of this RNase. We report here that C. diphtheriae DIP1463 encodes a predicted RnJ homolog, comprised of an N-terminal beta-lactamase domain, followed by beta-CASP and C-terminal domains. more...

(Submitter supplied) Previous findings have demonstrated that the NADH/NAD+ ratio has a strong impact on the glycolytic flux in C. glutamicum under anaerobic conditions in the absence of external electron acceptors. During an attempt to rewire anaerobic metabolism to achieve high yield formation of ethanol, we inactivated the malate dehydrogenase and lactate dehydrogenase in a C. glutamicum strain expressing pyruvate decarboxylase and alcohol dehydrogenase, to eliminate formation of the by-products succinate and lactate, respectively. 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...
