Quorum quenching N acyl homoserine lactonase

Quorum-quenching N-acyl-homoserine lactonase (EC 3.1.1.81, acyl homoserine degrading enzyme, acyl-homoserine lactone acylase, AHL lactonase, AHL-degrading enzyme, AHL-inactivating enzyme, AHLase, AhlD, AhlK, AiiA, AiiA lactonase, AiiA-like protein, AiiB, AiiC, AttM, delactonase, lactonase-like enzyme, N-acyl homoserine lactonase, N-acyl homoserine lactone hydrolase, N-acyl-homoserine lactone lactonase, N-acyl-L-homoserine lactone hydrolase, quorum-quenching lactonase, quorum-quenching N-acyl homoserine lactone hydrolase) is an enzyme with systematic name N-acyl-L-homoserine-lactone lactonohydrolase. This enzyme catalyses the following chemical reaction

Acyl-homoserine lactones are produced by numerous bacterial species. They use them to regulate the expression of virulence genes within their quorum-sensing process.
