Abstract excerpt
Virginiae butanolide (VB)-BarA of Streptomyces virginiae is one of the newly discovered pairs of a gamma-butyrolactone autoregulator and the corresponding receptor protein of the Streptomyces species, and has been shown to regulate the production of antibiotic virginiamycin (VM) in S. virginiae. A divergently transcribed barX gene is situated 259 bp upstream of the barA gene, and the BarX protein has been shown...
