TABLE 1.
Hydrophobic moment 〈μ〉 and polar angle Φ of KLAL, l11k12-KLAL and k9a10-KLAL calculated for an α-helical and a β-sheet secondary structure with different hydrophobicity scales
Peptide | 〈μ〉 (consensus) | 〈μ〉 (OMH) | 〈μ〉 (WRH) | Φ | |
---|---|---|---|---|---|
KLAL | α-helix | 0.334 | 0.120 | 0.377 | 80 |
β-sheet | 0.328 | 0.543 | 0.600 | ||
l11k12-KLAL | α-helix | 0.267 | 0.060 | 0.254 | 160 |
β-sheet | 0.214 | 0.419 | 0.422 | ||
k9a10-KLAL | α-helix | 0.296 | 0.105 | 0.375 | 75 |
β-sheet | 0.381 | 0.545 | 0.645 |
The angle ω between the amino acid side chains for the α-helix and the β-sheet structure was fixed at 100° and 167°, respectively. The mean hydrophobicity per residue, H, according to the different hydrophobicity scales of the peptides is −0.016 (consensus), 0.147 (OMH), and −0.344 (WRH).
