This enzyme belongs to the family of oxidoreductases, specifically those acting on the CH-OH group of donor with NAD+ or NADP+ as acceptor. The systematic name of this enzyme class is (R)[or (S)]-propane-1,2-diol:NAD+ oxidoreductase. Other names in common use include propanediol:nicotinamide adenine dinucleotide (NAD+) oxidoreductase, and L-lactaldehyde:propanediol oxidoreductase. This enzyme participates in pyruvate metabolism and glyoxylate and dicarboxylate metabolism.
