Structure of a pentameric virion-associated fiber with a potential role in Orsay virus entry to host cells
Fig 5
CP-δ forms particle associated fibers.
(a) EM images of Orsay VLPs containing CP-δ. Protruding fibers are highlighted by orange stars. Scale bar, 500 Å. (b) Length measurements of particle-associated fibers in comparison with the full-length δ fibers. (c) SDS-PAGE of the Orsay VLP. Western blot was performed using an anti-His antibody. (d) An Orsay capsid model with CP-δ fibers situated at the five-folds. On five-fold vertices, the CP portion and the δ portion of the CP-δ are shown in light green and orange respectively. The rest of the CP molecules in the capsid are shown in dark green. The Orsay, ~350-Å in diameter, and the CP-δ fiber, ~400-Å in length, are approximately drawn to scale.
