Effects of upstream DNA length on association of wild-type native RNAP with the lacUV5 promoter (30°C, 110 mM KCl buffer). (A) Promoter fragments were truncated at -130 (•), -100 (▿), -63 (○), or -45 (♦). The downstream end point for each promoter fragment was +40. Data are displayed as τ plots. (B) Kinetic constants derived by nonlinear analysis of the data (see also Fig. 10).
