This enzyme belongs to the family of oxidoreductases, specifically those acting on the aldehyde or oxo group of donor with NAD+ or NADP+ as acceptor. The systematic name of this enzyme class is betaine-aldehyde:NAD+ oxidoreductase. Other names in common use include betaine aldehyde oxidase, BADH, betaine aldehyde dehydrogenase, and BetB. This enzyme participates in glycine, serine and threonine metabolism.
