TL;DR: The structure of the reaction center from Rhodobacter sphaeroides has been solved by using x-ray diffraction at a 2.55-Å resolution limit and three lipid molecules that lie on the surface of the protein are resolved in the electron density maps, suggesting the presence of an “inner shell” of lipids around membrane proteins that is critical for membrane function.

TL;DR: The bacteriochlorophyll protein, or FMO protein, from Chlorobium tepidum, which serves as a light-harvesting complex and directs light energy from the chlorosomes attached to the cell membrane to the reaction center has been crystallized in a new space group.

TL;DR: In this study, carboxylate residues were introduced by mutagenesis into highly oxidizing reaction centers at a site homologous to the manganese-binding site of photosystem II, illustrating the successful design of a redox active metal center in a protein complex.

TL;DR: The binding of S-octyl-GSH to SjGST(Y7F) is enthalpically and entropically driven at temperatures below 30 degrees C and conformational changes that may be responsible for the lack of binding to the B subunit are observed.

TL;DR: Crystals have been obtained of reaction centers of the heterodimer mutant that has significantly different properties than wild type due to the primary donor being formed from both a bacterio chlorophyll and bacteriopheophytin rather than two bacteriochlorophylls as found for wild type.
