a The data were averaged over the entire simulation duration of 100 ns for each of the three runs and shown as means ± S.E.
b The occupancy values were presented as means ± S.D. of three different occupancies measured from three independent simulations within simulation time of 100 ns for each A1. θ is the α2-α1 interhelical angle of A1, and SASA denotes the average solvent-accessible surface area of the hydrophobic residues 553–556 in the β2-strand.
