Figure 5
Electron-density maps obtained ab initio at a resolution of 3.7 Å using the initial mask and the initial transfer matrices. The red meshes show the initial mask used; the blue lines show the backbones of the final refined model. (a) A cross-section view of the map for the T = 3 GNNV particle with the initial mask. The map was contoured at 1.5σ. (b) An enlarged view of the map for the S-domain and P-domain with the initial mask and the final model. (c) A view from the inside of the particle. An electron-density map for the S-domain parts can be clearly recognized. (d) A stereo map at 1.0σ for helices in the S-domain. |
