Superfamily Aldehyde Dehydrogenase; Chain A, domain 1
Functional Family NAD/NADP-dependent betaine aldehyde dehydrogenase

Enzyme Information

1.2.1.8
Betaine-aldehyde dehydrogenase.
based on mapping to UniProt Q8UH56
Betaine aldehyde + NAD(+) + H(2)O = betaine + NADH.
-!- In many bacteria, plants and animals, the osmoprotectant betaine is synthesized in two steps: (1) choline to betaine aldehyde and (2) betaine aldehyde to betaine. -!- This enzyme is involved in the second step and appears to be the same in plants, animals and bacteria. -!- In contrast, different enzymes are involved in the first reaction. -!- In plants, this reaction is catalyzed by EC 1.14.15.7, whereas in animals and many bacteria, it is catalyzed by either membrane-bound EC 1.1.99.1 or soluble EC 1.1.3.17. -!- In some bacteria, betaine is synthesized from glycine through the actions of EC 2.1.1.156 and EC 2.1.1.157.
