Protein
Betaine aldehyde dehydrogenase
Organism
Bacillus subtilis (strain 168)
Function
Involved in the biosynthesis of the osmoprotectant glycine betaine from choline (PubMed:8752328, PubMed:9297465). Catalyzes the oxidation of betaine aldehyde to betaine (PubMed:9297465). Shows specificity for betaine aldehyde as substrate. Can use both NAD(+) and NADP(+), but NAD(+) is strongly preferred (PubMed:9297465).
Similarity
Belongs to the aldehyde dehydrogenase family.
