Rice study measures physical effects of evolution at molecular scale A unique experiment at Rice University that forces bacteria into a head-to-head competition for evolutionary dominance has yielded new insights about the way Darwinian selection plays out at the molecular level. An exacting new analysis of the experiment has revealed precisely how specific genetic mutations impart a physical edge in the competition for survival. The new research, which could lead to more effective strategies...

Step towards designing fats that are digested more slowly Institute of Food Research scientists have discovered an unexpected synergy that helps break down fat. The discovery provides a focus to find ways to slow down fat digestion, and ultimately to create food structures that induce satiety. "Much of the fat in processed foods is eaten in the form of emulsions such as soups, yoghurt, ice cream and mayonnaise,"" said Dr Peter Wilde from the Institute of Food Research, an institute of BBSRC....

Scientists from the U.S. Department of Energy's Lawrence Berkeley National Laboratory have obtained the closest look yet of how a gargantuan molecular machine breaks down unwanted proteins in cells, a critical housekeeping chore that helps prevent diseases such as cancer. They pieced together the molecular-scale changes the machine undergoes as it springs into action, ready to snip apart a protein. Their work provides valuable clues as to how the molecular machine, a giant enzyme called...

LONDON, June 28 /PRNewswire/ -- During the economic slowdown in 2009, food enzymes were successfully positioned as cost savers and process efficiency improvers in many application segments. This strategy, along with increased R&D efforts, is expected to continue to attract new applications such as interesterification for the reduction of trans fats and as 'meat glue' (transglutaminases). While the increased use of enzymes in applications such as fruit and beverage processing and wine...

A new method of analyzing squalene and squalane, oils often used in the production of cosmetics and vaccines, can show whether they came originally from the liver oil of deepwater sharks or from olive oil. In 2006 the European Union imposed deep-sea shark fishing limits in the North-East Atlantic, and since 2008 some important cosmetic firms have declared that they have stopped using shark squalane. Up to now however there has been no way that a manufacturers could determine whether the...

'Smart' catalysts programmed to recognize specific molecular shape Using a rare metal that's not utilized by nature, Rice University chemists have created a synthetic enzyme that could help unlock the identities of thousands of difficult-to-study proteins, including many that play key roles in cancer and other diseases. The research was published online this week in the Journal of the American Chemical Society. "We have combined the chemical capabilities of rhodium with what biology already...

Suspecting that a particular protein in tuberculosis was likely to be vital to the bacteria's survival, Johns Hopkins scientists screened 175,000 small chemical compounds and identified a potent class of compounds that selectively slows down this protein's activity and, in a test tube, blocks TB growth, demonstrating that the protein is indeed a vulnerable target. This class of chemical compounds attacks TB by inhibiting methionine aminopeptidase (MetAP), an essential enzyme found in...
