Average helicity of spike tip residues over 500 ns of simulation. Cp149 shown in gray, Cp149-D78S shown in red. Secondary structure assigned by STRIDE [42]. Initial conformations for models AB and CD were from the respective quasi-equivalent dimers from a T=4 capsid (2G33 [43]). Model EF is from the crystal structure of an assembly incompetent dimer (3KXS [26]).
