Cedillo, Jorge A. Yañez-Santos, J. Antonio Ibarra, Javier Torres, Jorge A. Girón, James G. Fox, Miguel A. Ares

“…We determined the transcriptional expression of aroX and npsA, the first genes of each tilimycin (TM)/tilivalline (TV) biosynthetic operon in K. oxytoca MIT 09-7231 wild-type and its derivatives Δlrp mutant and complemented strains. Our results suggest that Lrp directly activates the transcription of both aroX and npsA genes by binding to the intergenic regulatory region in a leucine-dependent manner. …”
