Characteristics of the protein coding sequence
Acyl-homoserine lactonase
EN
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.

Additional Information
Plants modified for quorum quenching (degradation of quorum sensing signalling molecules) have been shown to convey increased protection to bacterial infection.
