TL;DR: The crystal structure of the light harvesting antenna complex (LH2) from Rhodopseudomonas acidophila strain 10050 showed that the active assembly consists of two concentric cylinders of helical protein subunits which enclose the pigment molecules as discussed by the authors.

TL;DR: The three-dimensional structure of human chorionic gonadotropin shows that each of its two different subunits has a similar topology, with three disulphide bonds forming a cystine knot, which is essential for receptor binding by the glyco-protein hormones.

TL;DR: A break in the crystal structure of the reaction center–light harvesting 1 (RC–LH1) core complex from Rhodopseudomonas palustris may provide a portal through which UQB can transfer electrons to cytochrome b/c1.

TL;DR: The calculated energy changes indicate that there may be significant contributions to inter-pigment energy interactions from molecular displacements and these may be of importance to photosynthetic energy transfer.

TL;DR: A NEW generation of whooping-cough vaccines contain P.69 pertactin, a surface-exposed domain of an outer membrane protein expressed by the virulent bacterium Bordetella pertussis1–3, a virulence factor that mediates adhesion to target mammalian cells, a reaction that is in part mediated by an RGB sequence.
