• PubMed Abstract: 
  

. Gene 3 protein (g3p), a minor coat protein from bacteriophage fd mediates infection of Escherichia coli bearing an F-pilus. Its N-terminal domain (g3p-D1) is essential for infection and mediates penetration of the phage into the host cytoplasm presumbly through interaction with the Tol complex in the E. coli membranes. Structural knowledge of g3p-D1 is both important for a molecular understanding of phage infection and of biotechnological relevance, as g3p-D1 represents the primary fusion partner in phage display technology.
