CC   -!- FUNCTION: P3 protein is necessary for adsorption onto host cells.
CC       Attaches to a type IV pilus of the host. {ECO:0000269|PubMed:15795287}.
CC   -!- SUBUNIT: Interacts with P6. {ECO:0000305|PubMed:6868373}.
CC   -!- SUBCELLULAR LOCATION: Virion membrane; Peripheral membrane protein.
CC       Note=The spike protein P3 protrudes from the membrane, where it is
CC       anchored by the integral membrane protein P6.
