In enzymology, a betaine-aldehyde dehydrogenase ( EC 1.2.1.8) is an enzyme that catalyzes the chemical reaction
- betaine aldehyde + NAD+ + H2O betaine + NADH + 2 H+
The 3 substrates of this enzyme are betaine aldehyde, NAD+, and H2O, whereas its 3 products are betaine, NADH, and H+.
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.
Structural studies
As of late 2007 [update], 4 structures have been solved for this class of enzymes, with PDB accession codes 1A4S, 1BPW, 1WNB, and 1WND.
