Acil-homoserin-lakton sintaza (EC 2.3.1.184, acil-homoserin laktonska sintaza, acil homoserin laktonska sintaza, acil-homoserinlakton sintaza, acilhomoserin laktonska sintaza, AHL sintaza, AHS, AHSL sintaza, AhyI, AinS, AinS protein, autoinducer sintaza, autoinducer sinteza protein rhlI, EsaI, ExpISCC1, ExpISCC3065, LasI, LasR, LuxI, LuxI protein, LuxM, N-acil homoserin lakton sintaza, RhlI, YspI, acil-(acil nosilac protein):S-adenozil-L-metionin aciltranseraza (formira lakton, otpušta metiltioadenozin)) je enzim sa sistematskim imenom acil-(acil-nosilac protein):S-adenozil-L-metionin aciltranseraza (formira lakton).[1][2][3][4][5][6][7][8][9] Ovaj enzim katalizuje sledeću hemijsku reakciju
- acil-[acil-nosilac protein] + S-adenozil-L-metionin [acil-nosilac protein] + S-metil-5'-tioadenozin + N-acil-L-homoserin lakton
Acil-homoserinske laktone formiraju brojne bakterijske vrste. Oni se koriste za regulaciju izražavanja gena virulencije u procesu poznatom kao očitavanje kvoruma.
