Figure 1

Overall structure of precontraction pyocin R2. (a,b) Electron microscopy images of the pyocin R2 embedded in uranyl acetate stain (a) or vitreous ice (b). One precontraction pyocin particle is boxed. (c) Surface view of a 3D montage reconstruction of the entire precontraction pyocin. (d–g) Surface views of the 3D reconstruction of pyocin trunk. Each view corresponds to the segmentation patterns illustrated at left. 3D models and density maps of the attachment helix of the sheath and β-sheet region of the tube are shown in Supplementary Videos 1–4.
