Acyl-homoserine-lactone acylase (EC 3.5.1.97, acyl-homoserine lactone acylase, AHL-acylase, AiiD, N-acyl-homoserine lactone acylase, PA2385 protein, quorum-quenching AHL acylase, quorum-quenching enzyme, PvdQ, QuiP) is an enzyme with systematic name N-acyl-L-homoserine-lactone amidohydrolase.
[1][2] This enzyme functions as a quorum quencher by catalysing the following chemical reaction Acyl homoserine lactones (AHLs) are produced by a number of bacterial species .
