Structural Transitions in the Polyalanine α-Helix under Uniaxial Strain.

We analyzed the response to strain of an infinite polyalanine chain in the α-helical conformation using density functional theory. Under compressive strain the π-helix is found to undergo structural transitions to a α-helix when the length of the helix is reduced by more than 10%. Under tensile stra...
