Fig 3. Structure of TFPs are trimeric, helical, and composed of three domains.

(A) Cartoon of R1 and R2-NTF constructs highlighting their relative location in the tail fiber and associated domains. Sequence similarity between R1 and R2-subtype tail fibers by region is also displayed (B) Trimeric R2-NTF structure surface rendering: chain A (green) wraps around chain B (beige) and chain C (light grey) in a relaxed helix. (C) R2-NTF single chain ribbon diagram. (D) Trimeric R1-NTF surface rendering showing three chains analogous to the chains of the R2-NTF. (E) R1-NTF single chain ribbon diagram.
