Stable type II' reverse turn - 310 helix conformation of Boc-D-Glu-Ala-Gly-Lys-Ala-Leu-OMe in apolar solvents.

Abstract The solution conformation of the title compound, based on one and two dimensional NMR techniques in CDCl 3 and (CD 3 ) 2 SO at 500 MHz, has been deduced as a 3 10 helix initiated by an electrostatically locked type II' reverse turn.
