Betaine-aldehyde dehydrogenase
In enzymology, betaine-aldehyde dehydrogenase is an enzyme that catalyzes the chemical reaction
The three substrates of this enzyme are glycine betaine aldehyde, oxidised nicotinamide adenine dinucleotide, and water. Its products are trimethylglycine, reduced NADH, and a proton.
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.
