Delineating the site of interaction on the pIII protein of filamentous bacteriophage fd with the F-pilus of Escherichia coli.

Abstract excerpt

The minor coat protein pIII at one end of the filamentous bacteriophage fd, mediates the infection of Escherichia coli cells displaying an F-pilus. pIII has three domains (D1, D2 and D3), terminating with a short hydrophobic segment at the C-terminal end. Domain D2 binds to the tip of F-pilus, which is followed by retraction of the pilus and penetration of the E. coli cell membrane, the latter involving an...
