For the first time, researchers have identified two important strategies for optimizing the effects of the enzymes involved in degrading persistent pollutants such as PCBs. These scientific advances, achieved by Professor Michel Sylvestre of Centre INRS—Institut Armand-Frappier in conjunction with U.S. and Indian researchers, will serve not only to help develop effective biocatalysts for resolving environmental pollution problems, but also to synthesize new chemical compounds of...

Journal of Biological Chemistry: Oxygen inactivates the enzyme function in three phases Scientists from the Faculty of Biology and Biotechnology at the RUB have published a report in the Journal of Biological Chemistry explaining why enzymes used for the production of hydrogen are so sensitive to oxygen. In collaboration with researchers from Berlin, they used spectroscopic methods to investigate the time course of the processes that lead to the inactivation of the enzyme's iron center....

Scientists Question Resveratrol Longevity Products

   New research suggests that anti-ageing face creams and supplements, that actively use a 'miracle ingredient' commonly found in red wine, are a complete waste of time and money, and do nothing to improve your odds of living a longer life. Resveratrol, which is credited with many of the health benefits of red wine, has become a staple for several beauty companies and is used in numerous products that can fetch prices of up to several hundreds of dollars for just a small...

Single amino acid exerts 'remote control' over double bond placement by desaturase enzymes Scientists at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory and collaborators at the Karolinska Institute in Sweden have discovered how an enzyme "knows" where to insert a double bond when desaturating plant fatty acids. Understanding the mechanism – which relies on a single amino acid far from the enzyme's active site – solves a 40-year mystery of how these enzymes...

With an eye toward understanding DNA replication, Cornell researchers have learned how a helicase enzyme works to actually unzip the two strands of DNA. (Nature, online Sept. 18, 2011.) At the heart of many metabolic processes, including DNA replication, are enzymes called helicases. Acting like motors, these proteins travel along one side of double-stranded DNA, prompting the strands to "zip" apart. What had been a mystery was the exact mechanics of this vital biological process...

JDRF-funded scientists collaborate with pharmaceutical company to uncover new ways to stimulate pancreatic beta cell growth One of the holy grails in diabetes research is to discover molecules that stimulate beta cell growth and to find drugs that target these molecules. Now, JDRF-funded researchers in collaboration with the pharmaceutical company Hoffmann-La Roche, have done both, discovering not only a protein that regulates beta cell growth, but also a chemical compound that stimulates...

Nutri-Med Logic Corp discusses the role of R-Alpha Lipoic and Omega-3 as a vehicle to improve the homeostasis. It has been suggested that redox imbalance causes alteration in the production of the protein Amyloid Beta pathways (gamma vs. alpha secretase) and that could be translated to the wrong vs. right amyloid protein synthesis in cases of Alzheimer / cognitive decline (PRWEB) August 06, 2011 Nutri-Med Logic Corp: Benefits of proper nutrition such as R-Alpha Lipoic and Omega-3 in...
