✦ 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.
