N-(3-Oxohexanoyl)-L-homoserine lactone (OHHL, N-(3-Oxohexanoyl)homoserine lactone) is a specific agonist of LuxR-type transcription factor CarR with a Kd of 1.8 µM. N-(3-Oxohexanoyl)-L-homoserine lactone activates CarR by inducing protein multimerization, promoting its binding to target DNA sequences in the carR-carA intergenic region, thereby upregulating the transcription of carbapenem biosynthesis genes. N-(3-Oxohexanoyl)-L-homoserine lactone acts as a quorum sensing signal molecule, enabling bacteria to coordinate the production of carbapenem antibiotics in a cell density-dependent manner. N-(3-Oxohexanoyl)-L-homoserine lactone is used to study bacterial quorum sensing mechanisms, especially the secondary metabolism and virulence factor regulatory pathways of Erwinia carotovora and Yersinia enterocolitica[1][2][3].
