DNA melting by RNA polymerase at the T7A1 promoter precedes the rate-limiting step at 37°C and results in the accumulation of an off-pathway intermediate
The formation of a transcriptionally active complex by RNA polymerase involves a series of short-lived structural intermediates where protein conformational changes are coupled to DNA wrapping and melting. We have used time-resolved KMnO(4) and hydroxyl-radical X-ray footprinting to directly probe c...
