Flagellar and translocation-associated type III secretion (T3S) systems are present in most
Gram-negative plant-and animal-pathogenic bacteria and are often essential for bacterial …

Spirochaetes, a phylum that includes medically important pathogens such as the causative
agents of Lyme disease, syphilis, and leptospirosis, are in many ways highly unique …

A central process in evolution is the recruitment of genes to regulatory networks. We
engineered immotile strains of the bacterium Pseudomonas fluorescens that lack flagella …

Helicobacter pylori uses flagellum-mediated chemotaxis to promote infection. Bacterial
flagella change rotational direction by changing the state of the flagellar motor via a …

The flagellum, a rotary engine required for motility in many bacteria, plays key roles in gene
expression. It has been known for some time that flagellar substructures serve as …

A single region of the Pseudomonas putida genome, designated the flagellar cluster,
includes 59 genes potentially involved in the biogenesis and function of the flagellar system …

The bacterial flagellum is a highly complex prokaryotic organelle. It is the motor that drives
bacterial motility, and despite the large amount of energy required to make and operate …

In many bacteria, LuxS functions as a quorum-sensing molecule synthase. However, it also
has a second, more central metabolic function in the activated methyl cycle (AMC), which …

Background LuxS may function as a metabolic enzyme or as the synthase of a quorum
sensing signalling molecule, auto-inducer-2 (AI-2); hence, the mechanism underlying …

The plant pathogenic bacterium Xanthomonas campestris pv. vesicatoria utilizes a type III
secretion (T3S) system to inject effector proteins into eukaryotic cells. T3S substrate …
