Figure 8.
Schematic representation of the contacts of CopG and RNAP with the DNA backbone of the Pcr promoter region at 37°C. RNAP contacts are denoted by red letters. Red arrows indicate positions in the RNAP–DNA complex with enhanced backbone cleavage. Contacts by CopG are shadowed in green. The SE is boxed. The binding sites of CopG dimers are indicated with brackets. The right half of the SE (RSE) is the CopG primary site. The −35 and extended −10 sequences of Pcr are denoted by lines and encircled letters in blue colour.
