To obtain a structure of TAP-RPo, we used a <scene name='73/733981/Cv/12'>nucleic-acid scaffold corresponding to positions –57 to +15</scene> (-54 to +11 shown) of a class II TAP-dependent promoter (positions numbered relative to transcription start site). Pink, nontemplate strand; red, template strand. The scaffold contained a <scene name='73/733981/Cv/13'>consensus DNA site for TAP centered between positions –41 and –42</scene> (TAP site: cyan, template strand; deeppink, nontemplate strand), a near-consensus <scene name='73/733981/Cv/23'>extended –10 element</scene> (violet), a <scene name='73/733981/Cv/15'>consensus –10 element</scene> (blue), a <scene name='73/733981/Cv/16'>consensus discriminator element</scene> (royalblue), a consensus core recognition element, a <scene name='73/733981/Cv/17'>13-bp transcription bubble</scene> (maintained in the unwound state by having noncomplementary sequences on nontemplate and template strands), and UpCpGpA (in magenta).
