Genetic element (GENE)
published: 09 Dec 2019 last updated: 06 Jan 2020
Acyl-homoserine lactonase CHB37EN
Protein coding sequence
AHL-lactonase CHB37 isolated from Bacillus cereus obtained from tomato rhizosphere soil in Malaysia.
The enzyme hydrolyzes N-acyl-homoserine lactones (AHLs) molecules secreted by Gram-negative bacteria, such as Erwinia mallotivora. AHLs have been determined to be the principle signalling molecule involved in quorum sensing (cell-to-cell communication) in Gram-negative bacteria and are essential for survival and regulation of virulence genes. Bacteria lacking AHLs are non-pathogenic.
Plants modified for quorum quenching (degradation of quorum sensing signalling molecules) have been shown to convey increased protection to bacterial infection.
