Members of this family, which are found in a set of hypothetical bacterial proteins, contain a core of six alpha-helices, where one central helix is surrounded by the other five. The exact function of this family has not, as yet, been determined [1]. The known structure shows this domain contains two copies of the histone fold [1].	Domain
