Regulation of ornibactin biosynthesis and N-acyl-L-homoserine lactone production by CepR in Burkholderia cepacia.
The CepR-CepI quorum-sensing system has been shown to regulate production of the siderophore ornibactin, extracellular proteases, and N-octanoyl-homoserine-L-lactone (OHL) in Burkholderia cepacia strain K56-2. To examine the effect of cepIR on production of other siderophores, cepR mutants were constructed in strains that produce pyochelin in addition to salicylic acid and ornibactins. Pc715j-R...
متن کاملTwo-component transcriptional regulation of N-acyl-homoserine lactone production in Pseudomonas aureofaciens.
Production of phenazine antibiotics by the biological control bacterium Pseudomonas aureofaciens 30-84 is regulated in part by the PhzI/PhzR N-acyl-homoserine lactone (AHL) response system (L. S. Pierson III, V. D. Keppenne, and D. W. Wood, J. Bacteriol. 176:3966-3974, 1994; D. W. Wood and L. S. Pierson III, Gene 168:49-53, 1996). Two mutants, 30-84W and 30-84.A2, were isolated and were found t...
متن کاملAcyl homoserine-lactone quorum-sensing signal generation.
Acyl homoserine lactones (acyl-HSLs) are important intercellular signaling molecules used by many bacteria to monitor their population density in quorum-sensing control of gene expression. These signals are synthesized by members of the LuxI family of proteins. To understand the mechanism of acyl-HSL synthesis we have purified the Pseudomonas aeruginosa RhlI protein and analyzed the kinetics of...
متن کاملAcyl-homoserine lactone degrading marine bacteria: Do they exist?
Acyl-homoserine lactones (acyl-HSL) are small molecules that are used in density dependent regulation in some bacteria. These molecules freely diffuse from the cell into the outside environment. Hence, it may be advantageous for other bacteria to utilize these molecules as a carbon source. The aim of this study is to look for acyl-HSL-utilizing bacteria in the marine environment. One strain, a ...
متن کاملStructural basis and specificity of acyl-homoserine lactone signal production in bacterial quorum sensing.
Synthesis and detection of acyl-homoserine lactones (AHLs) enables many gram-negative bacteria to engage in quorum sensing, an intercellular signaling mechanism that activates differentiation to virulent and biofilm lifestyles. The AHL synthases catalyze acylation of S-adenosyl-L-methionine by acyl-acyl carrier protein and lactonization of the methionine moiety to give AHLs. The crystal structu...
