Diversity and Distribution of N-Acylhomoserine Lactone (AHL)-Degrading Activity and AHL-Lactonase (AiiM) in Genus Microbacterium

N-Acylhomoserine lactone (AHL)-degrading enzyme, AiiM, was identified from the potato leaf-associated Microbacterium testaceum StLB037. In this study, we cloned eight aiiM gene homologues from other AHL-degrading Microbacterium strains. The similarity of the chromosomal locus of the aiiM gene is associated with the phylogenetic classification based on 16S rRNA. Degenerate PCR revealed that the ...

AhlD, an N-acylhomoserine lactonase in Arthrobacter sp., and predicted homologues in other bacteria.

Quorum sensing is a signalling mechanism that controls diverse biological functions, including virulence, via N-acylhomoserine lactone (AHL) signal molecules in Gram-negative bacteria. With the aim of isolating strains or enzymes capable of blocking quorum sensing by inactivating AHL, bacteria were screened for AHL degradation by their ability to utilize N-3-oxohexanoyl-L-homoserine lactone (OH...

Nocardioides kongjuensis sp. nov., an N-acylhomoserine lactone-degrading bacterium.

A Gram-positive, rod- or coccoid-shaped and N-hexanoyl-l-homoserine lactone-degrading bacterial strain, A2-4(T), was isolated from a soil in Korea, and its taxonomic position was investigated by using a polyphasic approach. Strain A2-4(T) grew optimally at pH 7.0-8.0 and 30 degrees C without NaCl. Phylogenetic analyses based on 16S rRNA gene sequences revealed that strain A2-4(T) is most closel...

AiiM, a novel class of N-acylhomoserine lactonase from the leaf-associated bacterium Microbacterium testaceum.

N-Acylhomoserine lactones (AHLs) are used as quorum-sensing signal molecules by many Gram-negative bacteria. We have reported that Microbacterium testaceum StLB037, which was isolated from the leaf surface of potato, has AHL-degrading activity. In this study, we cloned the aiiM gene from the genomic library of StLB037, which has AHL-degrading activity and shows high homology with the alpha/beta...

AidC, a novel N-acylhomoserine lactonase from the potato root-associated cytophaga-flavobacteria-bacteroides (CFB) group bacterium Chryseobacterium sp. strain StRB126.

N-acylhomoserine lactones (AHLs) are used as quorum-sensing (QS) signal molecules by many gram-negative bacteria. We have reported that Chryseobacterium sp. strain StRB126, which was isolated from the root surface of potato, has AHL-degrading activity. In this study, we cloned and characterized the aidC gene from the genomic library of StRB126. AidC has AHL-degrading activity and shows homology...
