AlphaGalileo Foundation Fungi serve as a kind of natural cleaning crew for the ecosystem. They form enzymes that can degrade hazardous substances, converting natural as well as man-made toxins into harmless compounds. For instance, they can help to break down synthetic dyes, which accumulate in great amounts during the production of textiles. Prof. Dr. Dietmar A. Plattner, Dr. Klaus Piontek, and Eric Strittmatter from the Institute of Organic Chemistry of the University of Freiburg and...

'Promiscuous' Enzymes Still Prevalent In Metabolism Shown By New Study

Challenges fundamental notion of enzyme specificity and efficiency Open an undergraduate biochemistry textbook and you will learn that enzymes are highly efficient and specific in catalyzing chemical reactions in living organisms, and that they evolved to this state from their “sloppy” and “promiscuous” ancestors to allow cells to grow more efficiently. This fundamental paradigm is being challenged in a new study by bioengineers at the University of California, San...

Enzymes involved in breaking down fat can now be manipulated to work three times harder by turning on a molecular switch recently observed by chemists at the University of Copenhagen. Being able to control this chemical on/off button could have massive implications for curing diseases related to obesity including diabetes, cardio vascular disease, stroke and even skin problems like acne. But the implications may be wider. Possibly the most important discovery in enzymology The results...

A new study presented today at the International Liver Congress 2012 demonstrates that the gut microbiota has a profound systemic effect on bile acid metabolism. Bile acids are synthesized from cholesterol in the liver and further metabolized by the gut microbiota into secondary bile acids. The main function of bile acid is to promote processing of dietary fat. In addition, hepatic synthesis of bile acids is a major mechanism of cholesterol breakdown in the body. Farnesoid-x-receptor (FXR)...

Concordia physicists modify battery-like enzyme to produce carbon-neutral energy New research at Concordia University is bringing us one step closer to clean energy. It is possible to extend the length of time a battery-like enzyme can store energy from seconds to hours, a study published in the Journal of The American Chemical Society shows. Concordia Associate Professor László Kálmán – along with his colleagues in the...

Light of specific wavelengths can be used to boost an enzyme's function by as much as 30 fold, potentially establishing a path to less expensive biofuels, detergents and a host of other products. In a paper published in The Journal of Physical Chemistry Letters, a team led by Pratul Agarwal of the Department of Energy's Oak Ridge National Laboratory described a process that aims to improve upon nature - and it happens in the blink of an eye. "When light enters the eye and hits the...
