- 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 edit
As of late 2007[update], 4 structures have been solved for this class of enzymes, with PDB accession codes 1A4S, 1BPW, 1WNB, and 1WND.
