(A) Schematic illustration of hydroxyproline-free ABC heterotrimer composed of (PKG)10, (DKG)10 and (EPG)10 peptides electrostatically stabilized through multiple lysine-aspartate and lysine-glutamate salt-bridges. All three peptides contain an N-terminal YG label to assist in determination of concentration. (B) Thermal melting profile of the individual, binary and ternary mixtures of (PKG)10, (DKG)10 and (EPG)10 peptide. The monomers as well as binary mixture were monitored at 225.0 nm and the ternary mixture was monitored at 222.4 nm.
