Figure 6
The crystal lattice of profilin:actin crystals (a) looking down x and (b) looking down z. In both views the direction of the actin ribbon formed in these crystals is along y and vertical. In (a) one complete actin ribbon is seen on the right half of the figure, composed of four profilins (black) and five actins (cyan, red, green, orange and blue). Domain 2 in the actin small domain is indicated with a dashed circle in magenta in part (a) and red in part (b). |
