Fig. 8. Secondary structure profile of a hypothetical protein encoded by a SNS repeating sequence ((SNS)n) deduced from structural indexes with the Kondo-Ikehara method (unpublished data). Open circles, shaded circles and closed circles in the lowere graph indicate beta-turn, alpha-helix and beta-sheet regions of the hypothetical protein, respectively. Thin lines in the upper graph represent the predicted beta-turn or coil regions of the hypothetical protein.
