#Unit 3. Fundamental Processes

Melting occurs between positions –11 and +2, with respect to the transcription start site.
In the case of the bacterial enzyme bearing s70, this transition, often called isomerization.
It requires energy derived from ATP hydrolysis and is instead the result of a nonspontaneous conformational change in the DNA– enzyme complex to a more energetically favorable form.
