AHL-lactonase SP24 isolated from Bacillus thuringiensis obtained from rice rhizosphere soil.
EN
Lactonase Enzyme
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.
EN
Plants modified for quorum quenching (degradation of quorum sensing signalling molecules) have been shown to convey increased protection to bacterial infection.
