Endophytic Actinomycetes: A Novel Source of Potential Acyl Homoserine Lactone Degrading Enzymes
Several Gram-negative pathogenic bacteria employ N-acyl-L-homoserine lactone (HSL) quorum sensing (QS) system to control their virulence traits. Degradation of acyl-HSL signal molecules by quorum quenching enzyme (QQE) results in a loss of pathogenicity in QS-dependent organisms. The QQE activity of actinomycetes in rhizospheric soil and inside plant tissue was explored in order to obtain novel...
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 کاملEndophytic Actinomycetes: A Novel Antibiotic Source
Antibiotics are secondary metabolites produced by some microorganisms to inhibit or kill many other microorganisms including different bacteria, viruses and eukaryotic cells. Antibiotics are secondary metabolites and these have also been termed “idiolites” (Walker, 1974). Subsequent and widespread use of antibiotics for therapeutic purposes regularly in human, veterinary and agricultural purpos...
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 کاملDraft Genome Perspective of Staphylococcus saprophyticus Strain SU8, an N-Acyl Homoserine Lactone-Degrading Bacterium
Staphylococcus saprophyticus strain SU8 was isolated from a pristine water source in Malaysia and it exhibited degradation of N-hexanoylhomoserine lactone. Here we report the draft genome sequence of S. saprophyticus strain SU8 to further understand its quorum quenching abilities.
