This family of proteins represents HapK, a protein of unknown function, with two homologues PigK and RedY. The monomer structure of the protein contains a four-stranded anti parallel beta-sheet, three alpha-helices and a short C terminal tail which it uses for dimer formation [1]. The surface of HapK has a deep cavity with consists of a kinked helix and a beta-four strand. HapK could be involved in prodigiosin biosynthesis, specifically the binding of a bipyrrole intermediate such as HBM or MBM [1]. Structure prediction suggests this protein is likely to form a homodimer adopting dimeric alpha/beta barrel fold.
