Glycerol, one of the most important by-products of alcoholic fermentation, has positive effects on the sensory properties of fermented beverages. It was recently shown that the most direct approach for increasing glycerol formation is to overexpress GPD1, which encodes the glycerol-3-phosphate dehyd

β¦ Synopsis
An NAD-dependent glycerol-3-phosphate dehydrogenase (sn-glycerol-3-phosphate:NAD+ oxidoreductase, EC 1.1.1.8) has been isolated and purified from Saccharomyces cerevisiae by affinity and exclusion chromatography. The enzyme was purified 5 1 OO-fold to a specific activity of 158. It has a molecular weight of approximately 31,000, a pH optimum between 6.8 and 7.2, and is sensitive to high-ionic-strength salt solutions. The enzyme is most strongly inhibited by phosphate and chloride ions.
