Photosynthesis - The Last Link In The Chain
2013-01-05 05:45:05

April Flowers for redOrbit.com - Your Universe Online For almost three decades, scientists have tried to identify a particular enzyme involved in regulating electron transport during photosynthesis. Now, a research team from Ludwig Maximilians Universitat (LMU) has found the missing link, which turns out to be not so new. All life on Earth is sustained by photosynthesis, a sunlight powered process that provides energy-rich compounds and the molecular oxygen that higher organisms depend...

Scientists from Queen Mary, University of London have discovered a mechanism that controls the way that organisms breathe or photosynthesize, potentially paving the way for improved biofuel production. Writing in the journal PNAS, Dr Lu-ning Lu and Professor Conrad Mullineaux from Queen Mary's School of Biological and Chemical Sciences report that by exposing cells to different light conditions, they have changed the way in which electrons are transported. Professor Mullineaux explains:...

Researchers at the RIKEN SPring-8 Center in Harima, Japan have clarified the crystal structure of quinol dependent nitric oxide reductase (qNOR), a bacterial enzyme that offers clues on the origins of our earliest oxygen-breathing ancestors. In addition to their importance to fundamental science, the findings provide key insights into the production of nitrogen oxide, an ozone-depleting and greenhouse gas hundreds of times more potent than carbon dioxide. As the central process by which...

Stress protection: How blue-green algae hoard energy Under normal conditions, cyanobacteria, also termed blue-green algae, build up energy reserves that allow them to survive under stress such as long periods of darkness. They do this by means of a molecular switch in an enzyme. By removing this switch, it should be possible to use the excess energy of the bacteria for biotechnological purposes such as hydrogen production, without the bacteria suffering. This was found out by researchers at...

The Terminator. The Borg. The Six Million Dollar Man. Science fiction is ripe with biological beings armed with artificial capabilities. In reality, however, the clunky connections between living and non-living worlds often lack a clear channel for communication. Now, scientists with the Lawrence Berkeley National Laboratory (Berkeley Lab) have designed an electrical link to living cells engineered to shuttle electrons across a cell's membrane to an external acceptor along a well-defined...

Specialized bacterial filaments shown to conduct electricity Some bacteria grow electrical hair that lets them link up in big biological circuits, according to a University of Southern California biophysicist and his collaborators. The finding suggests that microbial colonies may survive, communicate and share energy in part through electrically conducting hairs known as bacterial nanowires. "This is the first measurement of electron transport along biological nanowires produced by bacteria,"...

Researchers at UCLA's Jonsson Comprehensive Cancer Center and the departments of Chemistry and Biochemistry and Pathology and Laboratory Medicine have uncovered a role for an essential cell protein in shuttling RNA into the mitochondria, the energy-producing "power plant" of the cell.The import of nucleus-encoded small RNAs into mitochondria is essential for the replication, transcription and translation of the mitochondrial genome, but the mechanisms that deliver RNA into mitochondria remain...

By lending them a gene normally reserved for other classes of animals, researchers have shown they can rescue flies from their Parkinson's-like symptoms, including movement defects and excess free radicals produced in power-generating cellular components called mitochondria. The gene swap also protects healthy flies' mitochondria, and to a large extent the flies themselves, from the damaging effects of cyanide and other toxins, the team reports in the May issue of Cell Metabolism, a Cell...

Virginia Commonwealth University researchers have found that the protein Stat3 plays a key role in regulating mitochondria, the energy-producing machines of cells. This discovery could one day lead to the development of new treatments for heart disease to boost energy in failing heart muscle or to master the abnormal metabolism of cancer.In the study, published online Jan. 8 in Science Express, researchers reported that Stat3, a protein previously known to control the activity of genes by...
