pfam09123: DUF1931 (This model is not part of the current CDD release)
Domain of unknown function (DUF1931)
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. The known structure shows this domain contains two copies of the histone fold.
