Chloride complexation by heptapeptides: influence of C- and N-terminal sidechains and counterion.

Robert Pajewski1, Riccardo Ferdani, Paul H Schlesinger, George W Gokel.   

Abstract

The channel-forming diglycolylated heptapeptides containing the amino acid sequence Gly-Gly-Gly-Pro-Gly-Gly-Gly have been found to complex chloride in CDCl(3). The strength of the interaction depends on the terminal alkyl groups and on chloride's countercation.
