Photosystem 2

Cardona et al., in the advanced online edition of Molecular Biology and Evolution, examined the evolution origins of the D1 protein in cyanobacteria, which forms the heart of Photosystem II, the oxygen-evolving machine of photosynthesis. Photosystem II's (Nanowerk News) The protein complex known as photosystem II splits water molecules to release oxygen using sunlight and relatively simple biological building blocks. Although water can also be split artificially using an electrical voltage and a precious Photosynthesis is a plant's life source, and by taking a closer look at Researchers decided to take a closer look by extracting the photosystem II reaction centers from the leaves. Located in the chloroplasts of plant cells, photosystem II is the Fromme is the senior author and leader of the international team, which reported their work in “Serial time-resolved crystallography of photosystem II using a femtosecond X-ray laser,” in the July 9 online issue of Nature. Photosynthesis is one of the Located in the chloroplasts of plant cells, photosystem II is the group of proteins and pigments that does the photosynthetic heavy lifting. It's also the only known natural enzyme that uses solar energy to split water into hydrogen and oxygen. To get a During photosynthesis, plants, algae and some species of bacteria takes place at a metal complex which is embedded in a large membrane protein (photosystem II). This complex is composed of four manganese atoms (Mn) and one calcium atom (Ca), which .

Photosystem II is located in the chloroplasts of plant cells and is a group of proteins and pigments that does the "heavy lifting" when it comes to photosynthesis. It's also the only known natural enzyme that uses solar energy to split water into hydrogen Arizona State University researchers have recently revealed the water-splitting stages of photosynthesis in unprecedented detail. The study, entitled Serial time-resolved crystallography of photosystem II using a femtosecond X-ray laser, was published in The data show that no large scale structural changes (> 0.5·10−10 m) occur in the Mn4Ca cluster and the rest of the photosystem II complex during oxygen formation. The simultaneously collected X-ray emission data confirm that the "arresting" of the two Through photosynthesis, plants and some bacteria turn sunlight but it's hard to maintain that separation long enough to extract it to do useful work. In the photosystem II reaction center, that problem is nicely solved." The researchers used their .
