1H-NMR study of endothelin, sequence-specific assignment of the spectrum and a solution structure.
The solution conformation of the recently discovered bi-cyclic, 21 amino acid vasoconstrictor peptide, Endothelin I, has been examined by 1H-NMR in deuterated dimethyl sulphoxide. A full sequential assignment has been achieved. In addition, 19 long range NOEs were detected which were employed as distance constraints in molecular dynamics calculations to yield a possible solution structure for this new peptide.
