Activation Region II (ArII) Definition:
Region of CAP that is thought to bind to the amino-terminal domain (NTD) of the α-subunit of E. coli RNA polymerase..
Molecular Biology by Robert F. Weaver
Activation Region II (ArII) Notes:
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.
