Glycerol dehydrogenase

Glycerol dehydrogenase (EC 1.1.1.6, also known as NAD+-linked glycerol dehydrogenase, glycerol: NAD+ 2-oxidoreductase, GDH, GlDH, GlyDH) is an enzyme in the oxidoreductase family that utilizes the NAD+ to catalyze the oxidation of glycerol to form glycerone (dihydroxyacetone).

This enzyme is an oxidoreductase, specifically a metal-dependent alcohol dehydrogenase that plays a role in anaerobic glycerol metabolism and has been isolated from a number of bacteria, including Enterobacter aerogenes, Klebsiella aerogenes, Streptococcus faecalis, Erwinia aeroidea, Bacillus megaterium, and Bacillus stearothermophilus. However, most studies of glycerol dehydrogenase have been performed in Bacillus stearothermophilus, (B. stearothermophilus) due to its thermostability and the following structural and functional information will, therefore, refer primarily to the characterization of the enzyme in this bacterium.
