An Oak Ridge National Laboratory invention able to quickly predict three-dimensional structure of protein could have huge implications for drug discovery and human health. While scientists have long studied protein structure and the mechanism of folding, this marks the first time they are able to computationally predict three-dimensional structure independent of size of the protein. Because the invention also determines possible intermediate states in the protein folding process, it...

University of Michigan physicists used the electric fields generated by intersecting laser beams to trap and manipulate thousands of microscopic plastic spheres, thereby creating 3-D arrays of optically induced crystals. The technique could someday be used to analyze the structure of materials of biological interest, including bacteria, viruses and proteins, said U-M physicist Georg Raithel. Raithel is co-author of a research paper on the topic published online May 31 in the journal Physical...

A large number of illnesses stem from misfolded proteins, molecules composed of amino acids. Researchers at the University of Zurich have now studied protein misfolding using a special spectroscopic technique. Misfolding, as they report in Nature, is more frequent if the sequence of the amino acids in the neighboring protein domains is very similar. Proteins are the main molecular machines in our bodies. They perform a wide range of functions, from digesting and processing nutrients,...

Determining the molecular configuration of proteins is important in nanotechology, drug design, disease research and many other fields The structures of many protein molecules remain unsolved even after experts apply an extensive array of approaches. An international collaboration has led to a new, high-performance method that rapidly determined the structure of protein molecules in several cases where previous methods had failed. The usefulness of the new method is reported May 1 in Nature...

Medical therapies may be developed to recover healthy proteins that are important to prevent diseases such as Alzheimer's disease and diabetes ANN ARBOR, Mich., April 27, 2011 /PRNewswire-USNewswire/ -- A computer analysis by two University of Michigan researchers shows promise for helping develop therapies for some major diseases by rescuing proteins that have stopped performing normally. Understanding the role of protein molecules is vital for health research and finding cures and...

Whether you're talking about genes, or neurons, or the workings of a virus, at the most fundamental level, biology is a matter of proteins. So understanding what protein complexes look like and how they operate is the key to figuring out what makes cells tick. By harnessing the unique properties of polarized light, Rockefeller scientists have now developed a new technique that can help deduce the orientation of specific proteins within the cell. By turning their instruments toward the nuclear...

Enzymes are proteins that speed up chemical reactions, such as laundry detergent digesting protein stains, which are otherwise very difficult to remove. A research team led by Professor Kam-bo Wong of the Centre for Protein Science and Crystallography, School of Life Sciences at The Chinese University of Hong Kong demonstrated a fundamental principle in changing the activity of enzymes by means of protein engineering. The findings provide potential insights into the future design of...

The findings may enable scientists to better understand the molecular biology and biophysics of the brain and diseases such as Alzheimer's and Parkinson's A team of scientists from The Scripps Research Institute and the University of California, San Diego (UCSD) have developed a novel technique to observe previously unknown details of how folded structures are formed from an intrinsically disordered protein. The insights could help scientists to better understand the mechanism of plaque...

Arizona State University builds protein beam injector; contributes nanocrystalsUnraveling the molecular basis of life is an age-old quest of humanity. A breakthrough towards this goal was reported in a pair of studies published Feb. 3 in the scientific journal Nature, detailing a new method developed to determine structures of biomolecules based on diffraction from protein nanocrystals that are so small that they are not even visible under the microscope. A tiny aerojet nozzle provides a...

Scientists have invented a way to "Ëœwatch' proteins fold "” in less than thousandths of a second -- into the elaborate twisted shapes that determine their function. People have only 20,000 to 30,000 genes (the number is hotly contested), but they use those genes to make more than 2 million proteins. It's the protein molecules that domost of the work in the human cell. After all, the word protein comes from the Greek prota, meaning "of primary importance." Proteins are...
