摘要
An increased tendency to self-assemble is exhibited by helical peptides with a highly fluorinated interface embedded in phospholipid membranes. A simultaneously hydrophobic and lipophobic surface obtained by replacing all interface leucine residues with hexafluoroleucine results in a significant increase in the ability of transmembrane helices to form higher-order ensembles. A = fluorescence acceptor; D = fluorescence donor. (Figure Presented) © 2006 Wiley-VCH Verlag GmbH & Co. KGaA.
