Acyl-homoserine-lactone synthase (EC 2.3.1.184) is an enzyme with systematic name acyl-(acyl-carrier protein):S-adenosyl-L-methionine acyltranserase (lactone-forming, methylthioadenosine-releasing).[1][2][3][4][5][6][7][8][9] This enzyme catalyses the following chemical reaction
- acyl-[acyl-carrier protein] + S-adenosyl-L-methionine [math]\displaystyle{ \rightleftharpoons }[/math] [acyl-carrier protein] + S-methyl-5'-thioadenosine + N-acyl-L-homoserine lactone
Acyl-homoserine lactones (AHLs) are produced by a number of bacterial species and are used by them to regulate the expression of virulence genes in a process known as quorum-sensing.
