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.[1][2][3][4][5][6][7][8][9][10][11] This enzyme catalyses the following chemical reaction
- an N-acyl-L-homoserine lactone + H2O [math]\displaystyle{ \rightleftharpoons }[/math] an N-acyl-L-homoserine
Acyl-homoserine lactones are produced by numerous bacterial species. They use them to regulate the expression of virulence genes within their quorum-sensing process.
