Effects of lipid phase and inactivation ball peptide on secondary structure content of KV1 polypeptide.

Values shown are percentage contribution of each secondary structure class as estimated by curve-fitting infrared spectra amide I regions. Curve fitting was performed in GRAMS (Galactic) typically with 50 iterations and no parameter fixing. ‘α2' in the KV1, 30°C column corresponds to a broad peak centred at 1655 cm−1, assigned to a mixture of α-helix and/or non-ordered structures.
