Fig. 8: Tail fiber structure and attachment to the baseplate.
From: Cryo-EM analysis of Pseudomonas phage Pa193 structural components
a A cryo-micrograph of bacteriophage Pa193 reveals prominent and straight tail fibers. b Cartoon schematic of the baseplate assembly with the tail fibers (residues 1–340) attached to six vertices of the baseplate. c Cartoon representation of tail fiber gp47 AlphaFold2 trimeric assembly (residues 1–340) overlaid to the localized reconstruction (calculated at 3.3 Å resolution and displayed at 1.5 σ). d Zoom-in view of the interface between baseplate gp46 tail fiber attachment loop (green) and gp47 tail fiber loops (magenta). The red frame shows a zoom-in view of the hydrophobic core formed between gp46 (green) and gp47 (magenta).
