"Web15 Jun 2014 · The F-pilus assembly is composed of a hetero-oligomeric complex of TraV, TraK and TraB, with a tetradecameric ring of TraV forming an aperture in the outer membrane through which the pilus emerges (Silverman & Clarke, 2010). Presumably, TraV forms a tight seal around the pilus to prevent the loss of periplasmic contents to the media. " - The f pilus is
