Figure 1.
Electron density for the (a) W187A and (b) W187Y mutant of NS1A effector domain. (a) This is a section of a 2F0-Fc map contoured at 1σ to show the exposed CPSF30 binding pocket. (b) This is a section of a 2F0-Fc map contoured at 1σ to show the interface of the ED dimer due to crystallographic packing.
