This family of proteins includes SAV0927 from Staphylococcus aureus and similar proteins predominantly found in Firmicutes. This protein forms a structure that contains five dimers. Each protomer shows an anti-parallel five-stranded beta-sheet, with one strand from the other subunit in the dimer, and three alpha- helices at the C-terminal end. Its function is unknown [1].
