Use of an Inducible Promoter to Characterize Type IV Pili Homologues in Clostridium perfringens
… of <i>Clostridium perfringens</i>, a Gram-positive anaerobic pathogen, were lacking a tightlyregulated, inducible promoter system in their genetic toolbox. We constructed a lactose-inducible plasmid-based system utilizing the transcriptional regulator, BgaR. Using the <i>E. coli</i> reporter …

Investigating the Roles of the Stk Locus in Development, Motility and Exopolysaccharide Production in Myxococcus Xanthus
Myxococcus xanthus, a Gram-negative bacterium with a developmental cycle, displays a type IV pili (TFP) mediated surface motility known as social (S) gliding. Beside the polarly localized TFP, the fibril or extracellular polysaccharide (EPS) is also required for S-motility to function. It is …

Localization of Type IV Pilin Polymerization Proteins in Clostridium perfringens
… is a spore-forming anaerobic Gram-positive rod which has gliding motility through type IV Pili (TFP). Since the discovery of TFP in Gram-positive bacteria is relatively new, more studies are required to understand the mechanism and interaction of the proteins of this machinery. Moreover, …

Regulation of Exopolysaccharide Production in Myxococcus Xanthus
… extension and retraction of polarly localized type IV pili (Tfp). Besides Tfp, exopolysaccharides (EPS), another cell surface associated component, are also required for M. xanthus S motility. Previous studies demonstrated that the Dif chemotaxis-like signal transduction pathway is central to …

Biosynthesis of Nucleotide Sugar Monomers for Exopolysaccharide Production in Myxococcus Xanthus
… S motility requires two cellular structures: type IV pili (TFP) and exopolysaccharides (EPS). Previous studies have shown that M. xanthus does not use glucose or any other sugar as a primary carbon source. However, eight monosaccharides, namely glucose, mannose, arabinose, galactose, xylose, …
