From: Predicting the conformations of peptides and proteins in early evolution
Conformation | Conf. type | Native folded | Native unfolded | Native unfolded and denatured. | Early peptides. |
---|---|---|---|---|---|
α-helix | Reg.rep. | +++ |  |  | + |
β-sheet (as in native proteins) | Reg.rep. | +++ |  |  | ++ |
PPII (polyproline type II) | Reg rep | ++ | +++ | + | + |
nests | Enant | ++ | ++ | + | +++ |
amyloid (multi-layer) β-sheet | Reg.rep. |  |  | +++ | +++ |
(multi-layer)α-sheet | Enant. |  | + | ++ | +++ |
metal-peptide | Reg.rep. | + | + | + | ++ |
