Figure 3

Three-dimensional superimposition of hexamers (A) and pentamers (B) assembled from the HIV CA protein (orange ribbon, PDB entries 3h4e and 3p05), carboxysome shell protein (green ribbon, PDB entry 2a10) and lumazine synthase (cyan ribbon, PDB entry 2f59). The proteins assemble into large closed shell structures and share a cluster of positively charged arginines at the pentamer/hexamer ring centers. Hexamers and pentamers were superimposed using alpha carbons from the arginine rings, represented with a space filling model. Cα-Cα distances between adjacent arginines are shown.
