Activation Region II (ArII) Explanation

Activation region II is the region of CAP subunit, that binds to the NTD( amino terminal domain) of the RNA polymerase α-subunit in Escherichia coli. The primary σ factor, interacts with the activation regions II and III, at the relative positions to the transcription start site.
