The pathway of E. coli RNA polymerase-promoter complex formation as visualized by footprinting

Abstract

Figure 2: Footprints of RNA polymerase on the non-template strand of P VIII at different temperatures. "T" indicates that this lane contains a (dTMP)n ladder (20). Note that at 37° C denatured DNA was added after 11 min to visualize complex decay. For further details see legend to figure 1. © 1986 IRL Press Limited.
