The solution conformation of Endothelin-1, a recently discovered bicyclic, 21 amino acid peptide, has been examined by 1H NMR in deuterated dimethylsulphoxide and circular dichroism in aqueous and organic solvents. A total of 158 NOEs were detected, which were used as distance constraints in the distance geometry program DISGEO. Two families of structures were obtained, both characterized by a helix-like region extending from Lys9 to Cys15, but with opposite "handedness". Circular dichroism studies of the peptide in both aqueous and trifluoroethanol solutions show a negative shoulder at 224 nm, characteristic of right-handed helices. Molecular dynamics and energy minimization yielded a solution structure for this new peptide compatible with all experimental observations.
