General annotation (Comments)

Function

Catalyzes the NAD-dependent oxidation of glycerol to dihydroxyacetone (glycerone). Allows microorganisms to utilize glycerol as a source of carbon under anaerobic conditions. Exhibits a rather broad substrate specificity since it can also oxidize 1,2-propanediol and 2,3-butanediol and reduce dihydroxyacetone. Can not use NADP+ as an electron acceptor for the oxidation of glycerol.

Catalytic activity

Glycerol + NAD+ = glycerone + NADH.

Cofactor

Manganese.

Enzyme regulation

Inhibited by zinc.

Pathway

Polyol metabolism; glycerol fermentation; glycerone phosphate from glycerol (oxidative route): step 1/2.

Subunit structure

Homohexamer.

Sequence similarities

Belongs to the iron-containing alcohol dehydrogenase family.

Biophysicochemical properties

Kinetic parameters:

KM=1.27 mM for glycerol

KM=57 µM for NAD+
