AT base pairs called the DNA unwinding element (DUE).
IHF (integration host factor) and FIS (factor for inversion stimulation). These two proteins were discovered as required components of certain recombination reactions.
Another DNA-binding protein, HU (a histone like bacterial protein originally dubbed factor U), also participates but does not have a specific binding site.
