autoinducer synthetase for AHL

Synthesizes 3OC₆HSL, which binds to LuxR.

The lux cassette of V. fischeri contains a left and a right promoter. The right promoter gives weak constitutive expression of downstream genes.This expression is up-regulated by the action of the Lux repressor, LuxR. Two molecules of LuxR protein form a complex with two molecules the signalling compound HSL. This complex binds to a palindromic site on the promoter, increasing the rate of transcription.

Usage and Biology

Enzyme for creating acyl-homoserine lactones from normal cell metabolites. All LuxI proteins direct the synthesis of specific acyl-HSLs and show sequence similarity.
