Affinity cleavage of DNA by yTBP derivatives in the presence of yTFIIBc or yTFIIA′. (A) Autoradiogram of a 12% high resolution sequencing gel analyzing the products of affinity cleavage of the top strand of an 80-bp fragment of the AdMLP by K97C-OP in the presence of yTFIIBc. (B) Autoradiogram of a 12% high resolution sequencing gel analyzing the products of affinity cleavage of the top strand of an 80-bp fragment of the AdMLP by E188C-OP in the presence of yTFIIA′. (C) Histograms illustrating cleavage by K97C-OP at each base pair surrounding the AdMLP box in the presence of yTFIIBc or by E188C-OP at each base pair surrounding the AdMLP box in the presence of yTFIIA′.
