The protein is shown as Cartoons with Structure coloring. The a-helix is a magenta-colored spiral; the b-strands are yellow-colored arrows (pointing from the N- to the C-terminus); regular turns are colored light blue; and unspecified (mostly connecting) segments are colored white.

Color the hydrophobic sidechains green.
    These are mostly found in the interior of the protein.
Color the hydrophilic sidechains red.
    These are mostly on the solvent-exposed exterior of the protein.

Viewing tips:
Use the buttons to the right of the image to show only portions of the structure; then use the Chime menu to display or color the molecule. The rotate buttons act on the entire structure. Remove the distance monitors with a second click.
