Structure of the protein subunits in the photosynthetic reaction centre of Rhodopseudomonas viridis at 3Å resolution
TLDR
The molecular structure of the photosynthetic reaction centre from Rhodopseudomonas viridis has been elucidated using X-ray crystallographic analysis and the first description of the high-resolution structure of an integral membrane protein is presented.Abstract:
The molecular structure of the photosynthetic reaction centre from Rhodopseudomonas viridis has been elucidated using X-ray crystallographic analysis. The central part of the complex consists of two subunits, L and M, each of which forms five membrane-spanning helices. We present the first description of the high-resolution structure of an integral membrane protein.read more

Architecture of the Photosynthetic Oxygen-Evolving Center
TL;DR: The data strongly suggest that the OEC contains a cubane-like Mn3CaO4 cluster linked to a fourth Mn by a mono-μ-oxo bridge, and the details of the surrounding coordination sphere of the metal cluster and the implications for a possible oxygen-evolving mechanism are discussed.

Photoinhibition of photosystem II : inactivation, protein damage and turnover
TL;DR: Various protective mechanisms and an efficient repair cycle of Photosystem II allow plants to survive light stress and probably allows for coordinated biodegradation and biosynthesis of the D1 protein.

Atomic model of plant light-harvesting complex by electron crystallography
TL;DR: The structure of the light-harvesting chlorophyll a/b–protein complex, an integral membrane protein, has been determined at 3.4 Å resolution by electron crystallography of two-dimensional crystals.

MEMBRANE PROTEIN FOLDING AND STABILITY: Physical Principles
TL;DR: A coherent thermodynamic formalism for determining and describing the energetics of peptide-bilayer interactions and a review of the properties of the environment of membrane proteins--the bilayer milieu are reviewed.

TL;DR: The crystal structures of matrix porin and phosphoporin both reveal trimers of identical subunits, each subunit consisting of a 16-stranded anti-parallel β-barrel containing a pore.

A graphics model building and refinement system for macromolecules
TL;DR: A model building and refinement system is described for use with a Vector General 3400 display that has been used to assist in difference Fourier map interpretation at medium and high resolution, and to build a protein molecule into a multiple isomorphous replacement phased electron density map.

X-ray structure analysis of a membrane protein complex. Electron density map at 3 Å resolution and a model of the chromophores of the photosynthetic reaction center from Rhodopseudomonas viridis
TL;DR: In this paper, an atomic model of the prosthetic groups of the reaction center complex (4 bacteriochlorophyll b, 2 bacteriopheophytin b, 1 non-heme iron, 1 menaquinone, 4 heme groups) was built.
