FIG. 2.

Comparison of MNV and rNV VLP models. (A) Stereo, depth-cued rendering of MNV electron density going from blue (outside) to yellow (inside). Approximately, the P2 domains are blue, the P1 domains are green/cyan, and the shell domains are yellow/orange. (B) Stereo representation of a cross section of MNV with the same color radial cueing as in panel A. The approximate locations of the S, P1, and P2 domains are noted. The floating nature of the P domains is most notable in this view. (C) Calculated electron density of the P domains of the MNV model made by modifying the structure of rNV VLP. The A, B, and C subunits are blue, green, and red, respectively. To emphasize the differences in the orientation and positions, only the P domains were used in this calculation. (D) Representation of the calculated electron density of the rNV VLP P domains colored in the same manner as in panel C.
