Structure of Transportan in phospholipid bicellar solution
Overview
Transportan is a chimeric cell-penetrating peptide constructed from the, peptides galanin and mastoparan, which has the ability to internalize, living cells carrying a hydrophilic load. In this study, we have, determined the NMR solution structure and investigated the position of, transportan in neutral bicelles. The structure revealed a well-defined, alpha-helix in the C-terminal mastoparan part of the peptide and a weaker, tendency to form an alpha-helix in the N-terminal domain. The position of, the peptide in relation to the membrane, as studied by adding paramagnetic, probes, shows that the peptide lies parallel to, and in the head-group, region of the membrane surface. This result is supported by amide proton, secondary chemical shifts.
