(a) Surface-rendered model of the tail terminator/sheath assembly in ΦCD508 with subunits differentially coloured. The arrangement in the diffocin collar is similar but both collar (equivalent to the ΦCD508 tail terminator) and sheath subunits have fewer domains – see (b). (b) Individual collar/sheath components of ΦCD508 (right) and Av-CD291.2 (left). The ΦCD508 tail terminator protein (mauve) has an additional domain compared with the collar protein of Av-CD291.2 (pale green); PDB IDs 9gb7 (Wilson et al., 2025
