Secondary structure of peptides were determined by CD spectropolarimetry at increasing concentrations of TFE. Composition of secondary structures were obtained by deconvoluting CD spectra with CDSSTR algorithm using Dichroweb server using Basis set 4 as reference.

a

Helix is a mixture α- and 310-helices.

b

Initially, it was dissolved in 33% ACN in water.
