(a) Schematic diagram of a section through the C. difficile cell envelope. (b) Surface rendering of a model of a section of C. difficile S-layer viewed from outside the cell, with tightly packed SlpA subunits (PDB ID 7acy; Lanzoni-Mangutchi et al., 2022View full citation). HMW SlpA, green; LMW SlpA, cream; axes of twofold symmetry, blue stars. It is notable that the openings in the S-layer are not wide enough for the passage of either a phage or diffocin tail tube.
