Abstract

The specific interaction of the upstream element-containing promoter of the Escherichia coli acetate operon with either the RNA polymerase holoenzyme or its alpha subunit has been analyzed by the base removal method. Our results indicate that: (i) direct and specific base contacts can be detected in the acetate promoter-alpha subunit complex; (ii) base elimination in the upstream element of the acetate promoter enhances the binding of RNA polymerase. A similar effect is observed when studying the interactions between RNA polymerase and the rrnB ribosomal operon P1 promoter.
