Dynamic adhesion device of phage OE33PA drives Gram-positive host recognition

Laura Schmitt, Amel Chaïb, Denis Ptchelkine, Eaazhisai Kandiah, Claire Le Marrec, Christian Cambillau, Adeline Goulet

This study reports cryo-EM structures of phage OE33PA, revealing a dynamic adhesion device that mediates Gram-positive host recognition through receptor-binding proteins and a hexameric tape measure protein.
