- Research ArticleTripartite Regulation of the glpFKD Operon Involved in Glycerol Catabolism by GylR, Crp, and SigF in Mycobacterium smegmatis
Using genetic approaches, we first revealed that glycerol is catabolized through the glycolytic pathway after conversion to dihydroxyacetone phosphate in two sequential reactions catalyzed by glycerol kinase (GlpK) and flavin adenine dinucleotide (FAD)-containing glycerol-3-phosphate dehydrogenase (GlpD) in M. smegmatis. Our study also revealed that in addition to the...
- Research ArticleCidR and CcpA Synergistically Regulate Staphylococcus aureus cidABC Expression
This work focuses on the characterization of cis- and trans-acting elements essential for the induction of the cidABC operon in S. aureus. The results of this study are the first to demonstrate the synergistic control of cidABC expression by transcriptional regulators CidR and CcpA during carbohydrate metabolism. We established that...
- Research ArticleDNA Methylation by Restriction Modification Systems Affects the Global Transcriptome Profile in Borrelia burgdorferi
Lyme disease is the most prevalent vector-borne disease in North America and is classified by the Centers for Disease Control and Prevention (CDC) as an emerging infectious disease with an expanding geographical area of occurrence. Previous studies have shown that the causative bacterium, Borrelia burgdorferi, methylates its genome using restriction modification...
- MinireviewAfter the Fact(or): Posttranscriptional Gene Regulation in Enterohemorrhagic Escherichia coli O157:H7
To adapt to ever-changing environments, pathogens quickly alter gene expression. This can occur through transcriptional, posttranscriptional, or posttranslational regulation.
- Research Article | SpotlightComplex Control of a Genomic Island Governing Biofilm and Rugose Colony Development in Vibrio vulnificus
Biofilm and rugose colony formation are developmental programs that underpin the evolution of Vibrio vulnificus as a potent opportunistic human pathogen and successful environmental organism. A better understanding of the regulatory pathways governing theses phenotypes promotes the development and implementation of strategies to mitigate food chain contamination by...
