Structure of the Cytochrome b6f Complex of Oxygenic Photosynthesis: Tuning the Cavity
TLDR
The dimeric b6f complex from the thermophilic cyanobacterium Mastigocladus laminosus reveals a large quinone exchange cavity, stabilized by lipid, in which plastoquinone, a quin one-analog inhibitor, and a novel heme are bound. Expand
Structure of the electron transfer complex between ferredoxin and ferredoxin-NADP+ reductase
TLDR
The first crystal structure of the complex between maize leaf Fd and Fd-NADP+ oxidoreductase (FNR) is reported, suggesting that this type of molecular communication not only determines the optimal orientation of the two proteins for electron transfer, but also contributes to the modulation of the enzymatic properties of FNR.

The 2.8 Å crystal structure of the dynein motor domain
TLDR
This work reports the most complete structure obtained so far of the 380-kDa motor domain of Dictyostelium discoideum cytoplasmic dynein at 2.8 Å resolution and identifies a long-range allosteric communication pathway between the primary ATPase and the microtubule-binding sites. Expand
Atomic Structure of Plant Glutamine Synthetase
TLDR
The first crystal structures of maize GS reveal a unique decameric structure that differs significantly from the bacterial GS structure, and lead to a mechanism for the transfer of phosphate from ATP to glutamate and to interpret the inhibitory action of phosphinothricin as a guide for the development of new potential herbicides. Expand
X-ray crystal structure of the light-independent protochlorophyllide reductase
TLDR
A unique trans-specific reduction mechanism is proposed in which the distorted C17-propionate of Pchlide and an aspartate from BchB serve as proton donors for C18 and C17 of PChlide, respectively. Expand
The structure of BtuB with bound colicin E3 R-domain implies a translocon
TLDR
The absence of a channel and the peripheral binding of R135 imply that BtuB serves to bind the colicin, and that the coiled-coil delivers the Colicin to a neighboring outer membrane protein for translocation, thus forming a colicIn translocon. Expand

TLDR
Impacts of the recently developed universal wwPDB OneDep deposition/validation/biocuration system and various methods-specific ww PDB Validation Task Forces on improving the quality of structures and data housed in the PDB Core Archive are described together with current challenges and future plans. Expand
Chlorophyll biosynthesis: spotlight on protochlorophyllide reduction.
TLDR
This review discusses the two fundamentally different mechanisms of Pchlide reduction in photosynthetic organisms, Rhodobacter capsulatus and Rhodob bacteria. Expand
Structures of cyanobacteriochromes from phototaxis regulators AnPixJ and TePixJ reveal general and specific photoconversion mechanism
TLDR
Cyanobacteriochromes are cyanobacterial tetrapyrrole-binding photoreceptors that share a bilin-binding GAF domain with photoreCEPTors of the phytochrome family that are representative of subclasses showing red-green-type and blue/green- type reversible photoconversion, respectively. Expand
The 2.8-Å Crystal Structure of the Dynein Motor Domain
TLDR
The crystal structure of the 380-kDa motor domain of Dictyostelium cytoplasmic dynein is reported, which shows details of functional units constituting the motor domain, such as the ATP-hydrolyzing ring composed of six AAA+ modules, the long coiled-coil microtubule-binding stalk, and the force-generating rod-like linker.
