This domain, is an internally duplicated structure with a novel fold [1]. It comprises two similar units that are arranged such that the two -helices pack together in the centre, crossing at an angle of 34 degrees, sandwiched between the two three-stranded, antiparallel beta-sheets. The overall domain is thus constructed as a beta-alpha-beta three-layer sandwich [1].
