Abstract

In marked contrast to the most favourable folded conformation, predicted from ab initio quantum mechanical calculations, the crystal structure analysis of the model system incorporating CONHCH2CH2CONH moiety, revealed the existence of an all-anti conformation, characterized by the backbone torsion angles: φ ≈ −146°, μ ≈ 172° and ψ ≈ 155°. Potential applications of the residue to form highly ordered, novel β-sheet like structure(s) with distinct faces have been suggested.
