Impact of 2,3 α-helical amino acid residues on the stability of the helical-structure
We established a α-helix motif method by using computer software exploited by ourselves to do a statistical analysis of the structures of 967 non-redundant protein sequences.We also extended the Chou-Fasman rules.As a result,we found that α-helix in the second and third amino acid residues commonly affect its structural stability.
