摘要：

Four kinds of the repeated pentapeptide sequences were synthesized in order to obtain the information on the torsion angles of the backbone of two Val residues (Val14 and Val16) and one Gly residue (Gly15) using both 2D spin-diffusion NMR under off magic angle spinning (OMAS). Moreover, the local conformation of the Gly15 residue was analyzed in detail from the comparison of the calculated and observed 2D spin-diffusion NMR spectra.
