Energy transfer in an LH4-like light harvesting complex from the aerobic purple photosynthetic bacterium Roseobacter denitrificans
2011, Biochimica et Biophysica Acta - BioenergeticsCitation Excerpt :A spectrally similar complex B800–B830 was also found in Chromatium (Chr.) purpuratum [7]. In response to low light conditions, another purple bacterium, Chr.
Carotenoid-bacteriochlorophyll energy transfer in LH2 complexes studied with 10-fs time resolution
2006, Biophysical JournalCitation Excerpt :We therefore used chromatophore membranes rather than the isolated LH2 complex. Previous studies (34) showed that the LH2 complex represents >90% of the pigment-protein complexes in C. purpuratum membranes under the cell growth conditions used for our samples. In this case, no sample degradation was detected.
Circular dichroism of carotenoids in bacterial light-harvesting complexes: Experiments and modeling
2004, Biophysical JournalCitation Excerpt :acidophila strain 10050 and Rsp. molischianum were grown anaerobically in the light and harvested as previously reported (Cogdell and Thorber, 1979; Cogdell et al., 1983, 1990; Cogdell and Crofts, 1990; Evans et al., 1990; Cogdell and Hawthornthwaite, 1993; Halloren et al., 1995). Isolation and purification of the antenna complexes were performed as described in Cogdell and Hawthornthwaite (1993).
Absorption and CD spectroscopy and modeling of various LH2 complexes from purple bacteria
2002, Biophysical JournalCitation Excerpt :The two LH2 complexes also differ in the carotenoid molecules which, however, have the same orientations in both structures with only minor deviations close to the B850 BChls. Earlier CD studies of purple bacterial antenna systems indicate that the types of LH2 complexes found can vary greatly (Cogdell and Scheer, 1985). Here we report the results of a comprehensive comparison study by means of absorption and circular dichroism spectroscopy of LH2 complexes from many different species.
