Enzyme Information
| 1.2.1.3 | Aldehyde dehydrogenase (NAD(+)). based on mapping to UniProt P56533 An aldehyde + NAD(+) + H(2)O = a carboxylate + NADH. -!- Wide specificity, including oxidation of D-glucuronolactone to D-glucarate. -!- Formerly EC 1.1.1.70. | 
| 1.2.1.8 | Betaine-aldehyde dehydrogenase. based on mapping to UniProt P56533 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. |
