Part:BBa_M13008
M13KO7 gene VIII
This gene is part of the bacteriophage M13 genome. It encodes the major coat protein, with approximately 2700 copies of the protein on each phage particle. The protein is first synthesized at a longer precursor protein that is clipped between the Alanines at positions 23 and 24. It is possible to silently add a Pst site to clone fusions upstream and in frame with Ala that begins mature protein. Small peptide-fusions are possible to the N-terminal portion of the mature p8 (phage display systems are built around this finding) but addition of more than 6 or 8 residues makes the phage pack poorly, leading to unproductive infections.

The p8 is the major coat protein, wrapping all the filamentous phage. This proteins is very useful and used in phage display when experimenting on phage M13.
