This domain is found in Tail spike protein (TSP) from Shigella phage Sf6 and similar sequences from tailed bacteriophages and bacterial prophages. It forms a beta-sandwich formed by two antiparallel, three stranded beta-sheets. A short alpha helix is included in the connecting loop between the third and fourth strand. This domain is structurally homologous to viral coat proteins [1].	Domain
