Photophysiological and photosynthetic complex changes during iron starvation in Synechocystis sp. PCC 6803 and Synechococcus elongatus PCC 7942. [PDF]
Iron is an essential component in many protein complexes involved in photosynthesis, but environmental iron availability is often low as oxidized forms of iron are insoluble in water.

Advances in the Understanding of the Lifecycle of Photosystem II
Photosystem II is a light-driven water-plastoquinone oxidoreductase present in cyanobacteria, algae and plants. It produces molecular oxygen and protons to drive ATP synthesis, fueling life on Earth.

Electron crystallography of photosystem II has revealed the location of important subunits and photoactive pigment molecules within this large membrane protein complex. It has also demonstrated a close evolutionary link among all types of photosynthetic reaction centres.

Specific association of photosystem II and light‐harvesting complex II in partially solubilized photosystem II membranes [PDF]
In this study, we report the structural characterization of photosystem II complexes obtained from partially solubilized photosystem II membranes. Direct observation by electron microscopy, within a few minutes after a mild disruption of the membranes with the detergent n‐dodecyl‐α,d‐maltoside, revealed the presence of several large supramolecular ...

The extrinsic proteins of Photosystem II
In this review we examine the structure and function of the extrinsic proteins of Photosystem II. These proteins include PsbO, present in all oxygenic organisms, the PsbP and PsbQ proteins, which are found in higher plants and eukaryotic algae, and the PsbU, PsbV, CyanoQ, and CyanoP proteins, which are found in the cyanobacteria.

Photosystem II assembly from scratch [PDF]
Construction of a functional Photosystem II (PSII) in cyanobacteria and chloroplasts depends on the action of auxiliary factors, which transiently interact with PSII intermediates during assembly. In addition to a common PSII structure and a conserved set of PSII assembly factors, cyanobacteria, and higher plants have evolved additional, clade-specific

Photoinactivation of Photosystem II in Prochlorococcus and Synechococcus. [PDF]
The marine picocyanobacteria Synechococcus and Prochlorococcus numerically dominate open ocean phytoplankton. Although evolutionarily related they are ecologically distinct, with different strategies to harvest, manage and exploit light.
