Fig. 3: Comparison of the two different conformations of HTNV-L protomers.

a Surface structure colored as in Fig. 2 showing the conformation of protomer A, present in the isolated apo dimer and in the external dimers of the hexamer, and protomer B, present in the central dimer of the hexamer. The rotations between both conformations are indicated. Two views that differ by 90° are displayed. b Zoom on the conformation of the C-terminal region of conformers A and B. Domain rotations and translations are indicated. A dotted line represents the position of the cap-binding domain (CBD) of the central dimer.
