RESUMO
A binding site for integration host factor (IHF) was identified upstream of the aceBAK promoter. Under inducing conditions, IHF activates aceB::lacZ expression by opposing IclR repression. In contrast, IHF has little effect on aceB::lacZ expression under repressing conditions. The ability of IHF to relieve repression under inducing but not repressing conditions allows this protein to amplify the induction of aceBAK.
