|Overall Architecture of Peptostreptococcal Protein L.|
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.
The exchange of amide protons (N-H) with solvent D2O was studied by Yi and Baker, Protein Sci5, 1060-1066 (1996) using NMR and mass spectrometry. The NMR experiments showed that the exchange rates fell into three classes.
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.
