Method Effects of lac repressor on the extent of formation and the kinetics of association and dissociation of abortively-initiating open complexes (RPinit) were examined using fluorescence detected abortive initiation and KMnO4 chemical probing.
Comments Lac repressor bound to a suitably placed lac operator sterically inhibits functional binding (open complex formation) of RNA pol to its promoter in its activated state 1000 fold
