title: Human beta-endorphin. 270-MHz 1H-nuclear-magnetic-resonance study of glycyl residues in aqueous solution.
abstract: 1H spectra at 270 MHz of the beta h-endorphin glycyl residues in aqueous solution are reported. The chemical shifts, coupling constants and temperature coefficients are compared with those of the glycyl residues in Met-enkephalin and in a random coil model peptide. The local conformation of Tyr-Gly-Gly-Phe-segment observed in Met-enkephalin is maintained in beta h-endorphin.
