Frequencies of the patterns for consecutive λ type dihedral angles when λ type dihedral angle was split into four regions. The bar diagram shows the observed numbers of the 16 different patterns of two consecutive λ type angles, λi–λi+1. Here, all λ type angles were split into four regions, i.e. A = 0° to 90°, B = 90° to 180°, −A = −90° to 0°, and −B = −90° to −180°; 16 patterns were generated from the combinations for two consecutive λ type angles, λi-λi+1, and finally the numbers of the patterns in the 103 non-homologous proteins were measured. Error bars were the standard deviations estimated by bootstrap method, resampling the data 500 times with replacement and repeating the analysis44.
