Function

[G3P_BPM13] Plays essential roles both in the penetration of the viral genome into the bacterial host via pilus retraction and in the extrusion process. During the initial step of infection, G3P mediates adsorption of the phage to its primary receptor, the tip of host F-pilus. Subsequent interaction with the host entry receptor tolA induces penetration of the viral DNA into the host cytoplasm. In the extrusion process, G3P mediates the release of the membrane-anchored virion from the cell via its C-terminal domain.

Publication Abstract from PubMed

The structure of the two N-terminal domains of the gene 3 protein of filamentous phages (residues 1-217) has been solved by multiwavelength anomalous diffraction and refined at 1.46 A resolution. Each domain consists of either five or eight beta-strands and a single alpha-helix. Despite missing sequence homology, their cores superimposed with a root-mean-square deviation of 2 A. The domains are engaged in extensive interactions, resulting in a horseshoe shape with aliphatic amino acids and threonines lining the inside, delineating the likely binding site for the F-pilus. The glycine-rich linker connecting the domains is invisible in the otherwise highly ordered structure and may confer flexibility between the domains required during the infection process.
