Three-dimensional structure of cyanobacterial photosystem I at 2.5 Å resolution
The structure of photosystem I from the thermophilic cyanobacterium Synechococcus elongatus described here provides a picture at atomic detail of 12 protein subunits and 127 cofactors comprising 96 chlorophylls, 2 phylloquinones, 3 Fe4S4 clusters, 22 carotenoids, 4 lipids, a putative Ca2+ ion and 201 water molecules.
Crystal structure of photosystem II from Synechococcus elongatus at 3.8 Å resolution
The X-ray structure of photosystem II is described on the basis of crystals fully active in water oxidation, shows how protein subunits and cofactors are spatially organized and the larger subunits are assigned and the locations and orientations of the cofacters are defined.
Femtosecond X-ray protein nanocrystallography
This work offers a new approach to structure determination of macromolecules that do not yield crystals of sufficient size for studies using conventional radiation sources or are particularly sensitive to radiation damage, by using pulses briefer than the timescale of most damage processes.
Structure of photosystem I.
Lipidic cubic phase injector facilitates membrane protein serial femtosecond crystallography.
This work presents a technique for extruding gel-like LCP with embedded membrane protein microcrystals, providing a continuously renewed source of material for serial femtosecond crystallography.

An improved structural model of the photosystem I complex from the thermophilic cyanobacterium Synechococcus elongatus is described at 4 A resolution. This represents the most complete model of a…
High-Resolution Protein Structure Determination by Serial Femtosecond Crystallography
Serial femtosecond crystallography (SFX) is applied using an x-ray free-electron laser (XFEL) to obtain high-resolution structural information from microcrystals of the well-characterized model protein lysozyme, demonstrating the immediate relevance of SFX for analyzing the structure of the large group of difficult-to-crystallize molecules.

Crystal structure of rhodopsin bound to arrestin by femtosecond X-ray laser
The crystal structure of a constitutively active form of human rhodopsin bound to a pre-activated form of the mouse visual arrestin is determined by serial femtosecond X-ray laser crystallography and provides a basis for understanding GPCR-mediated arrestin-biased signalling.
Structure of cyanobacterial Photosystem I
This review discusses the complex function of Photosystem I based on the structure of the complex at 2.5 Å resolution as well as spectroscopic and biochemical data.
