Figure 1
Electron microscopy of bacteriophage T5 tails. (a) Negative-stain electron microscopy image. Arrows indicate the central straight tail fibres (stf; made up of the pb5 protein), while asterisks indicate the lateral L-shaped tail fibres (ltf; made up of the pb1 protein). One of the beaded distal rods of the L-shaped tail fibre is boxed. The bar indicates 50 nm. (b) Three-dimensional model of the ltf distal rod domain. Domain numbers and their proposed border residues are indicated; D1 corresponds to the proximal thin rod domain (not shown). |
