Tailspike protein from Shigella phage Sf6 specifically mediates the attachment to their hosts. Its structure revealed a conserved architecture with a central, right-handed beta-helix. The C-terminal domain adopts a beta-sandwich fold, is represented in this entry, and is reminiscent of viral capsid proteins [1,2].	Domain
