A novel low-light (LL) adapted light-harvesting complex II has been isolated from Rhodopseudomonas palustris. Previous work has identified a LL B800-850 complex with a heterogeneous peptide composition and reduced absorption at 850 nm. The work presented here shows the 850 nm absorption to be contamination from a high-light B800-850 complex and that the true LL light-harvesting complex II is a novel B800 complex composed of eight alpha beta(d) peptide pairs that exhibits unique absorption and… CONTINUE READING
