Pigment Protein Complex

LH2 from the purple photosynthetic bacteriumMarichromatium(formerly known asChromatium)purpuratumis an integral membrane pigment–protein complex that is involved in harvesting light energy and transferring it to the LH1–RC `core' complex. The purified LH2 complex was crystallized using the sitting-drop vapour-diffusion method at 294 K. The crystals diffracted to a resolution of 6 Å using synchrotron radiation and belonged to the tetragonal space groupI4, with unit-cell parametersa=b= 109.36,c= 80.45 Å. The data appeared to be twinned, producing apparent diffraction symmetryI422. The tetragonal symmetry of the unit cell and diffraction for the crystals of the LH2 complex from this species reveal that this complex is an octamer.
