Physiochemical studies on interactions between DNA and RNA polymerase. Unwinding of the DNA helix by Escherichia coli RNA polymerase.

In a medium containing 10mM Tris, pH 8, 10 mM MG++, 50 mM K+ and 10 mM NH4, the binding of an E. coli RNA polymerase holoenzyme unwinds the DNA helix by about 240 degrees at 37 degrees C. In this medium the total unwinding of the DNA increases linearly with the molar ratio of polymerase to DNA. The...
