Fig. 7. Atomic structural model of a chromatophore vesicle.

Fig. 7

A. The vesicle comprises 67 LH2 complexes (green), 11 LH1-RC-PufX dimers & 2 RC-LH1-PufX monomers (blue/red), 4 cytbc1 dimers (magenta), and 2 ATP synthases (orange) (see movie in Supplementary Information). B. ATP production rate for steady state illumination as a function of incident light intensity for the vesicle shown (solid line) and for a reference vesicle containing only one cytbc1 dimer complex but 7 additional LH2 complexes to maintain vesicle surface area (dashed line). At a typical low light intensity of 30 W/m2 the vesicle produces 119 ATP/s, the rate increasing slowly to 158 ATP/s at a saturating intensity of 1 kW/m2.
