Figure 2.

Non-canonical conformations identified by the descriptor search engine in the bovine rhodopsin primary structure: helical regions are shown in red letters and non-helical regions in black. For this run, LogProb_thres was set to –26 and P was set to 7; see text for a description of the parameters. For this choice of parameters, the search engine correctly identified all the non-canonical elements that can be identified in the bovine rhodopsin crystal while generating no false hits. The identified non-canonical features are shown by color-coding: green, π-helix; pink, 3₁₀-helix; yellow, proline- or non-proline-induced kink. See also text for a discussion.
