Proline-Aromatic Sequences Stabilize Turns via C–H/π interactions in both cis-Proline and trans-Proline [PDF]
, 2023 In proteins, proline-aromatic sequences exhibit increased frequencies of cis-proline amide bonds, via proposed C–H/π interactions between the aromatic ring and either the proline ring or the backbone C–Hα of the residue prior to proline.
