Regulatory RNAs at the Heart of Sugar Metabolism: New Mechanisms and Novel Discoveries
… in diverse cellular processes such as energy metabolism, stress response, biofilm formation, and pathogenesis. In the Gram-positive bacterium Bacillus subtilis, several RNA elements have been shown to be required for the precise coordination of genes involved in various sugar utilization …

In situ studies of sugar metabolism in Ricinus communis L. and Saccharum officinarum L.
… is regulated in the endosperm is still unknown. Sugarcane is a very important food crop. Sugarcane yellow leaf virus leads to sugarcane yellow syndrome and reduces the sugar production. Starch accumulation was found in the virus-infected plants. Within the starch staining, the results indicate …

CcpA-Mediated Carbon Catabolite Repression of Virulence in the Group A Streptoccus
… investigates the role of the primary mediator of sugar metabolism regulation, carbon catabolite control protein (CcpA), in the regulation of virulence of the GAS. A putative CcpA-binding site or catabolite response element (cre) was identified upstream of the promoter for the virulence gene …

An Investigation Into Splicing Variation and Expression Patterns of Insulin-Like Peptide 4 (ILP4) Within the Drosophila Genus
… to mammalian insulin and its role in regulating sugar metabolism. In this study, we investigate a novel splicing variation within the Drosophila takahashii Insulin-Like Peptide 4 (ILP4) gene. Our investigation identified a splicing variation found in four Drosophila species that introduces an …

Strain-resolved transcriptomics: exploring functional heterogeneity of the gut microbiota in health and disease
… of genes involved in stress response, sugar metabolism pathways, and antimicrobial resistance. Notably, we identified transcriptionally active but genomically low-abundance taxa, highlighting the importance of measuring the transcriptional activities of strains beyond species …

Targeted and untargeted metabolomic profiling of human serum, urine and brain by liquid chromatography mass spectrometry (LC-MS)
… and N-acetyl aspartyl glutamate (NAAG) and sugar metabolites sorbitol, gluconic acid, xylitol, ribitol, arabinotol, and erythritol.;For the determination of the sugar polyols it was necessary to develop and new GC-MS method. There appears some commonality between metabolic perturbations …

Low-grade aldehyde stress protects mice from diet-induced obesity
… suppressor screen revealed that glucose and fat metabolism mediate aldehyde toxicity indirectly and change cellular fitness as measured by growth without changing aldehyde levels in cells. Further investigating the role of aldehyde-stress in combination with fat and sugar metabolism *in vivo*, I …

Small molecule profiling and imaging of the zebra finch song system
… amino acids (i.e. glutamate) and in energy metabolism (i.e. glucose). Metabolomic studies focusing on the auditory lobule, a brain region involved in the acquisition, processing, and interpreting of auditory inputs, exhibited unique metabolomic profiles between birds exposed to novel song …

Studies on the stress response in Fusobacterium nucleatum.
… of periodontitis and is thought to occur by the metabolism of nutrients supplied by gingival crevicular fluid. Studies have shown that F. nucleatum is partly responsible for the rise in pH and have concluded that in comparison to other plaque inhabitants, F. nucleatum has the greatest ability to …

Regulation der Synthese der Glukosamin-6-Phosphat Synthase GlmS in Escherichia coli durch das neuartige Protein YhbJ
Aminozucker sind essentielle Bausteine des Lebens, die in Bakterien vorallem als Vorläufer der Zellwandbiosynthese dienen. Ihre de novo-Synthese beginnt mit der Umsetzung von Fruktose-6-Phpsophat und Glutamin zu Glukosamin-6-Phosphat und Glutamat. Diese Reaktion wird durch die Glukosamin-6-Phosphat …
