FIG. 6. Image processing of various two-dimensional
views of the CP43'-PSI supercomplex. a, a selection of nine
typical class averages taken from 76 different class averages
used for the threedimensional reconstruction. b, surface-rendered
views of the final three-dimensional map calculated by angular
reconstitution viewed from the same angles presented in a. c,
Fourier-shell correlation at 3 sigma * (square root 3) gives
a resolution of 24 Å for the three-dimensional model. Bar represents
20 nm.
