Abstract excerpt
The expI-expR locus drives a quorum-sensing system in the phytopathogenic bacterium, Erwinia chrysanthemi. Purified ExpR, an N-acyl homoserine lactone-responsive regulatory protein, binds to the promoter/operator region of the expI and expR genes. DNase I footprinting experiments showed that ExpR...
