  1. The propensity for the middle four positions are calculated for the sequences containing minimum 12 amino acids. The first middle position represent the fifth position in the sequence from the N-terminus end. The amino acids at each position are arranged in descending order of their propensities. The kinked and curved helix do not have sequences more than length 8 and do not figure out in this list.
