Figure 7
CD analysis of P2. (a) CD spectra in buffer (dashed line) and in DMPC/DMPG liposomes (1:150 protein:lipid, thin line). The difference spectrum between these samples is shown as a dotted line and the OCD spectrum of P2 in oriented membranes is shown as a thick line. (b, c) Thermal stability of P2 in solution (b) and of membrane-bound P2 (c). For clarity, CD spectra are shown at intervals of 10 K from 293 to 363 K. |
