It is comprised of two subunits, A and B, which are homologous. The structure of ectatomin reveals that each subunit is comprised of two helices and a connecting hinge region, the forms a hairpin structure that is stabilised by disulphide bridges. The two hinges are connected by a disulphide bond [1].	Domain
