The rotation function for 2 Zn insulin at 6 Å resolution. The space group was R3 with a = 82.5 and c = 34.0 Å in the hexagonal setting. (a) A stereographic projection down the c axis showing the R = 180° section. The a and b axes are indicated by the straight lines. The NCS peak is at ψ = 90, φ = 44°. (b) The line through the rotation function at ψ = 90, φ = 44° as a function of κ. [Reprinted with permission from Dodson et al. (1966). Copyright (1966) Academic Press.] |
