The chimeric peptide [Lys(-2)-Arg(-1)]-sarafotoxin-S6b, composed of the endothelin pro-sequence and sarafotoxin, retains the salt-bridge staple between Arg(-1) and Asp8 previously observed in [Lys(-2)-Arg(-1)]-endothelin. Implications of this salt-bridge in the contractile activity and the oxidative folding reaction.

We have previously shown that the carboxylate-state structure of KR-ET-1 is more constrained and stabilized by a salt bridge between Arg(-1) and the Asp8 or Glu10 side chain [Aumelas et al. (1995) Biochemistry 34, 4546-4561]. ...For the non-native isomer, we measure …
