Blue light activates new enzyme reaction

Enzymes are the driving forces behind chemical reactions in living cells. They are therefore also called biocatalysts and are used in biotechnological processes to enable reactions. Scientists at the Westfälische Wilhelms-Universität Münster (WWU) and the University of Pavia have now discovered an enzyme that has a mechanism that is so far unknown in this combination: In addition to its normal function, blue light can trigger another reaction, but this requires the presence of a specific molecule, as the team reports in the technical journal

Vanilla aroma from lignin

Vanillin gives the vanilla bean its characteristic flavor. It is one of the most frequently used flavoring substances in food and perfume production, but also in the production of pharmaceuticals. Several tens of thousands of tons are used annually. Until now, however, artificially produced vanillin has been made from petroleum, creating toxic waste. Researchers at the Johannes Gutenberg University in Mainz (JGU) have now succeeded in developing a sustainable method for obtaining the coveted aroma substance. A team led by Siegfried Waldvogel used the biopolymer lignin - a wood component tha
