EM reconstructions of T5 tail before and after interaction with FhuA. Negative stain (a, b, c) and cryo-EM (d, e, f) images, and cryo-EM 3D reconstruction (side views (g, h, i) and top view (j, k, l)) of T5 tails before (6.2 Å resolution, a, d, g, j) and after (5.8 Å resolution, b, e, h, k) interaction with FhuA, and of pb6 tubes (8.8 Å resolution, c, f, i, l). Scale bar, 20 nm
