: Evidence of local conformational difference between disulfide and diselenide
Conformations of disulfide and diselenide were compared in (Boc‐Cys/Sec‐NHMe)2 and (Boc‐Cys/Sec‐OMe)2 using X‐ray crystallography, nuclearmagneticresonance (NMR) spectroscopy, density functional theory (DFT), and circular dichroism (CD) spectroscopy. Conformations of disulfide/diselenide in polypeptides are defined based on the sign of side chain torsion angle χ3 (–CH2–S/Se–S/Se–CH2–); negative indicates
