Figure 8: Modelling of the effect of LH1 removal on the position of YFP and the energy-transfer distances.

Figure 8

(a) The RC/YFP–LH1 complex shown is adapted from the data in Fig. 3. The subunits are: LH1β (blue), LH1α (yellow), PufX (red), RC-M (magenta), RC-H (cyan) and RC-L (orange). YFP is in gold, with its chromophore in orange. The RC special pair of BChls is shown in red. The 85 Å distance between the YFP chromophore and the RC BChl dimer in a is shown to shorten when the surrounding LH1 complex is removed during purification of the RC, down to a minimum of 45 Å in b.
