Enzyme Information

1.2.1.8
Betaine-aldehyde dehydrogenase.
based on mapping to UniProt P49419
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.
1.2.1.31
L-aminoadipate-semialdehyde dehydrogenase.
based on mapping to UniProt P49419
(S)-2-amino-6-oxohexanoate + NAD(P)(+) + H(2)O = L-2-aminoadipate + NAD(P)H.
-!- (S)-2-amino-6-oxohexanoate undergoes a spontaneous dehydration forming the cyclic (S)-2,3,4,5-tetrahydropyridine-2-carboxylate, which serves as a substrate for the hydrogenation reaction.
1.2.1.3
Aldehyde dehydrogenase (NAD(+)).
based on mapping to UniProt P49419
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.
