CD investigation of porphyrin-porphyrin interaction with links to acyclic beta-sheet peptide self-assembled in an aqueous media
Amphiphilic peptide, Ac-Cys(Por)-Lys-Val-(-Ser-Val-)(n)-Lys-Val-NH2 (n = 0 or 1, Cys(Por) = side-chain porphyrin-linked Cys), self-assembled to form the beta -sheet in buffer solution-2,2,2-trifluoroethanol and showed exciton coupled Cotton effects in the porphyrin region due to the closely oriented porphyrins.
