Intrinsic terminators—that is, those that do not require auxiliary rho factor (r), as described shortly—require a GC–rich hairpin to form in the secondary structure of the RNA being transcribed.

Activators that stimulate this kind of promoter work by triggering a conformational change in either RNA polymerase or DNA; that is, they interact with the stable closed complex and induce a conformational change that causes transition to the open complex. This mechanism is an example of allostery.
