Figure Legend Snippet: B factors (Panel A) were calculated from the aqueous simulations for TH-(1-43) (black line) and THp-(1-43) (red line) and from the peptide/membrane simulations for TH-(1-43) (blue line) and THp-(1-43) (green line), and are represented as a function of residue number. Panel B: Representative structure of THp-(1-43) which shows the intrapeptide sidechain-sidechain hydrogen bonds with occupancies >25% (dashed lines) in the aqueous simulation. The peptide is coloured as a continuous gradient going from blue (N-terminal) to red (C-terminal). The last 100 ns of each simulation were used for both analyses.
Techniques Used:
Figure Legend Snippet: A) Representative sensorgrams for the interaction of TH-(1-43) with POPS liposomes on a L1 sensor chip at increasing concentrations of peptide. B) Peptide concentration dependency of TH-(1-43) (black) and THp-(1-43) (red) when bound to POPS liposomes. RUs were measured as a function of peptide concentration. S0.5 values were extracted from the hyperbolic, single-rectangular, two-parameter curve fitting and resulted in S0.5 of 53.3 ± 9.2 µM and 48.2 ± 7.4 µM for TH-(1-43) and THp-(1-43), respectively. C) Far-UV CD spectra of 40 µM TH-(1-43) (black lines) or THp-(1-43) (red lines) without (solid lines) or with (dotted lines) POPS liposomes (0.6 mM phospholipid). Samples were prepared in 10 mM Na-Hepes, 150 mM NaCl, pH 7.4, and spectra were recorded at 25 °C.
Techniques Used: Concentration Assay
Figure Legend Snippet: TH-(1-43)/POPS is presented in panels A and B, and THp-(1-43)/POPS is presented in panels C and D. Panels A and C show the peptide – coloured as a continuous gradient going from blue (N-terminal) to red (C-terminal) – together with most of the peptideinteracting leaflet of the POPS bilayer, the orange spheres representing the head group phosphorus atoms. Panels B and D provide close-ups of the most important hydrogen bond interactions (dashed lines) in each case, where the relevant TH residues are displayed as ball-and-stick models and the POPS lipids as sticks. Water and ions have been removed for clarity.
Techniques Used:
Figure Legend Snippet: The energies are computed using 1000 frames extracted from the last 100 ns of each peptide/membrane simulation (systems D and E in Table 1). ΔGdecomp = ΔG’ – ΔGnon-polar. The black bars represent the energies derived for each residue in TH-(1-43), and the grey bars are the THp-(1-43) equivalents. A) Sorted by amino acid sequence; B) Sorted in ascending order according to the TH-(1-43) decomposition energies.
Techniques Used: Derivative Assay, Sequencing
