Acyl-homoserine lactone-based quorum sensing in the Roseobacter clade: complex cell-to-cell communication controls multiple physiologies
نویسندگان
چکیده
Bacteria have been widely reported to use quorum sensing (QS) systems, which employ small diffusible metabolites to coordinate gene expression in a population density dependent manner. In Proteobacteria, the most commonly described QS signaling molecules are N-acyl-homoserine lactones (AHLs). Recent studies suggest that members of the abundant marine Roseobacter lineage possess AHL-based QS systems and are environmentally relevant models for relating QS to ecological success. As reviewed here, these studies suggest that the roles of QS in roseobacters are varied and complex. An analysis of the 43 publically available Roseobacter genomes shows conservation of QS protein sequences and overall gene topologies, providing support for the hypothesis that QS is a conserved and widespread trait in the clade.

Acyl-Homoserine Lactone Quorum Sensing in the Roseobacter Clade
Members of the Roseobacter clade are ecologically important and numerically abundant in coastal environments and can associate with marine invertebrates and nutrient-rich marine snow or organic particles, on which quorum sensing (QS) may play an important role. In this review, we summarize current research progress on roseobacterial acyl-homoserine lactone-based QS, particularly focusing on thr...
متن کاملBacterial Quorum Sensing and Its Application in Biotechnology
Many bacteria use small diffusible signalling molecules called Autoinducers to communicate each other termed as Quorum Sensing. The signalling molecules in grampositive bacteria are oligopeptides, in gramnegative bacteria are Nacyl homoserine lactone and a family of auto inducers known as auto inducer2 in both grampositive and gramnegative bacteria. These molecules are internalized in the cell ...
متن کاملBiochemical Detection of N-Acyl Homoserine Lactone from Biofilm-Forming Uropathogenic Escherichia coli Isolated from Urinary Tract Infection Samples
Background: N-Acyl homoserine lactone (AHL) is found to be the main component of quorum sensing (QS) in Gram-negative bacteria and plays an important role in biofilm formation. Little information is available regarding the role of AHL in biofilm formation in Escherichia coli (E. coli). The purpose of this investigation was to biochemically detect and characterize AHL activity in biofilm-forming...
متن کاملQuorum Sensing: It’s About Time
Quorum sensing is a form of cell-to-cell communication by which bacteria communicate by secreting signaling molecules called autoinducers that help regulate gene expression. Quorum sensing was first detected in Photobacterium fischeri [1]. A specific acylated homoserine lactone was found to regulate transcription of the luciferase operon resulting in light emission [2]. A related organism, Vibr...
متن کاملNew structural variants of homoserine lactones in bacteria.
N-Acylhomoserine lactones (AHLs) are used by a wide variety of bacteria for cell-cell communication in "quorum-sensing". These compounds are derived from L-homoserine lactone and a fatty acid, which varies in chain-length, degree of saturation, and the presence or absence of an oxygen atom at C-3. In this study we describe for the first time the occurrence of acyl chains carrying a methyl branc...
