Molecular cloning and regulation of expression of the genes for initiation factor 3 and two aminoacyl-tRNA synthetases.

abstract：:Acyl-homoserine lactone (acyl-HSL) quorum-sensing signaling is common to many Proteobacteria. Acyl-HSLs are synthesized by the LuxI family of synthases, and the signal response is mediated by members of the LuxR family of transcriptional regulators. Burkholderia thailandensis is a member of a closely related cluster o...
