Bacterial pili are involved in a host of activities, including motility, adhesion, transformation, and immune escape. Structural studies of these pili have shown that several distinctly different classes exist, with no common origin. Remarkably, it is now known that the archaeal flagellar filament appears to have a common origin with the bacterial type IV pilus, and assembly in both systems involves hydrophobic N-terminal alpha-helices that form three-stranded coils in the center of these… CONTINUE READING
