ExsA is an AraC-type transcriptional activator protein that is regulated through protein-protein interactions rather than small molecule ligands. Prior to infection, ExsA is inhibited through a direct interaction with the anti-activator ExsD. Upon host cell contact this interaction is disrupted by the anti-antiactivator protein ExsC. The regulatory domain of ExsA mediate ExsD binding and is represented by this entry. The structure of this domain closely resembles those of the regulatory domains of AraC and ToxT, having typical cupin-like fold [1].	Domain
