Genetic identification of chemotactic transducers for amino acids in Pseudomonas aeruginosa.
Two chemotactic transducer genes (termed pctB and pctC) and an open reading frame (orf1) were found in the pctA-flanking region which was previously identified as a chemotactic transducer gene inExpand
Statistical Analysis of Pseudomonas aeruginosa Biofilm Development: Impact of Mutations in Genes Involved in Twitching Motility, Cell-to-Cell Signaling, and Stationary-Phase Sigma Factor Expression
ABSTRACT Four strains of Pseudomonas aeruginosa (wild type, ΔpilHIJK mutant, lasI mutant, and rpoS mutant) were genetically tagged with the green fluorescent protein, and the development of flowExpand
Involvement of an Extracellular Protease in Algicidal Activity of the Marine Bacterium Pseudoalteromonassp. Strain A28
ABSTRACT The marine bacterium Pseudoalteromonas sp. strain A28 was able to kill the diatom Skeletonema costatum strain NIES-324. The culture supernatant of strain A28 showed potent algicidal activityExpand
Role of Inorganic Polyphosphate in Promoting Ribosomal Protein Degradation by the Lon Protease in E. coli
Inorganic polyphosphate (polyP), a polymer of hundreds of phosphate (Pi) residues, accumulates inEscherichia coli in response to stresses, including amino acid starvation. Here we show that theExpand
Chemotaxis proteins and transducers for aerotaxis in Pseudomonas aeruginosa.
It was previously shown that the chemotaxis gene cluster 1 (cheYZABW) was required for chemotaxis. In this study, the involvement of the same cluster in aerotaxis is described and two transducerExpand
Alginate synthesis by Pseudomonas aeruginosa: a key pathogenic factor in chronic pulmonary infections of cystic fibrosis patients.
Pulmonary infection by mucoid, alginate-producing Pseudomonas aeruginosa is the leading cause of mortality among patients suffering from cystic fibrosis. Alginate-producing P. aeruginosa is uniquelyExpand
Identification and characterization of two chemotactic transducers for inorganic phosphate in Pseudomonas aeruginosa.
Two chemotactic transducers for inorganic phosphate (P(i)), designated CtpH and CtpL, have been identified in Pseudomonas aeruginosa. The corresponding genes (ctpH and ctpL) were inactivated byExpand
Inhibition of Quorum Sensing in Pseudomonas aeruginosa by N-Acyl Cyclopentylamides
ABSTRACT N-Octanoyl cyclopentylamide (C8-CPA) was found to moderately inhibit quorum sensing in Pseudomonas aeruginosa PAO1. To obtain more powerful inhibitors, a series of structural analogs ofExpand
Inhibition of Quorum Sensing in Serratia marcescens AS-1 by Synthetic Analogs of N-Acylhomoserine Lactone
ABSTRACT Quorum sensing is a regulatory system for controlling gene expression in response to increasing cell density. N-Acylhomoserine lactone (AHL) is produced by gram-negative bacteria, which useExpand
Bacterial phosphonate degradation, phosphite oxidation and polyphosphate accumulation
Large quantities of xenobiotic phosphonates (Pn), which are used as pesticides, detergent additives, antibiotics, and flame retardants, are released into the environment. These C-P compounds areExpand
