2. Figure 1
The N-terminal domain of the retroviral capsid protein. (a) RSV, (b) HIV-1. The β hairpin is shown in detail, in an orientation that is slightly different from that of the whole domain. The boundaries of the helices within the N-terminal domain of RSV CA are: helix 1, 15–30; 2, 33–44; 3, 49–61; 4, 62–87; 5, 102–107; 6, 116–124; 7, 125–147. Helix definitions incorporate the N- and C-terminal capping residues. Coordinates for the N-terminal domain of HIV-1 CA were taken from the X-ray structure of the molecule in complex with cyclophilin A [3]. The program Ribbons 2.0 [50] was used in the preparation of the figure.

3. Figure 2
The twofold symmetric interaction between CA1–154 molecules seen within the crystal. (a) The interaction involves the parallel packing of helix 4 from adjacent molecules. Although the distal part of the β hairpin and one of the surface loops are not completely ordered in one copy of the molecule, this is not shown. (b) Details of the interface. The sidechain atoms Ala64, Ala67, Leu68 and Asp71 are shown in ball-and-stick representation. Asp71 in both molecules is coordinated to a bridging metal ion, most likely Mg2+. The program Ribbons 2.0 [50] was used in the preparation of the figure.

4. Figure 3
A stereo-diagram showing 19 conformers representing the solution structure of the C-terminal domain of RSV CA. Only the backbone atoms (N, C, Cα) are displayed. The boundaries of the helices within the C-terminal domain of RSV CA are: helix 1, 163–177; 2, 181–197; 3, 198–208; 4, 214–226. Helix definitions incorporate the N- and C-terminal capping residues. The program Molscript [51] was used in the preparation of the figure.

5. Figure 4
Surface properties of the C-terminal domain. (a) Schematic representation of the C-terminal domains of four retroviral CAs (top). Corresponding representations of the molecular surface (bottom). Regions of the molecular surface arising from non-polar amino acids (G,A,P,V,I,L,F,M,C,W [52]) are colored blue. (b) This figure displays the same information as in (a) but the domains have been rotated by 180° so that the reverse face of the molecule is visible. For clarity, the N terminus has been truncated at an equivalent point in each structure (Asp155 in RSV, Asp152 in HIV-1, Asn152 in EIAV, Ser135 in HTLV-1). Several residues N-terminal to this position should be considered part of the C-terminal domain and are potentially involved in domain association [6,8]. Ribbon diagrams were prepared using the program Ribbons 2.0 [50], and molecular surfaces were calculated and displayed using the programs MSMS and MSV [53]. Vertices of the triangulated surface were colored by the property of the closest atom. The Protein Data Bank accession codes of the structural models used to generate the figure are 1a43 (HIV-1 [8]), 1eia (EIAV [9]), 1qrj (HTLV-1 [10]).

6. Figure 5
Two discrete modes of assembly for RSV CA. (a) TEM image of part of a planar array of RSV CA, negatively stained with uranyl acetate. The planar array curls up, forming partially closed tubular structures, at the sheet boundaries (indicated with dark arrows). (b) TEM image of tubes of RSV CA, apparently formed from a toroidal oligomer. The specimen has been negatively stained with uranyl acetate. Free oligomers are indicated with dark arrows.
