The host-binding domain of the P2 phage tail spike reveals a trimeric iron-binding structure

The adsorption and infection of bacteriophage P2 is mediated by tail fibres and tail spikes. The tail spikes on the tail baseplate are used to irreversibly adsorb to the host cells. Recently, a P2 phage tail‐spike protein, gpV, was purified and it was shown that a C‐terminal domain, Ser87–Leu211, is...
