| FUNCTION | Involved in the biosynthesis of the osmoprotectant glycine betaine. Catalyzes the irreversible oxidation of betaine aldehyde to the corresponding acid. |
| CATALYTIC ACTIVITY | Reaction=betaine aldehyde + H2O + NAD(+) = glycine betaine + 2 H(+) + NADH; Xref=Rhea:RHEA:15305, ChEBI:CHEBI:15377, ChEBI:CHEBI:15378, ChEBI:CHEBI:15710, ChEBI:CHEBI:17750, ChEBI:CHEBI:57540, ChEBI:CHEBI:57945; EC=1.2.1.8; PhysiologicalDirection=left-to-right; Xref=Rhea:RHEA:15306; |
| COFACTOR | Name=K(+); Xref=ChEBI:CHEBI:29103; Note=Binds 2 potassium ions per subunit.; |
| PATHWAY | Amine and polyamine biosynthesis; betaine biosynthesis via choline pathway; betaine from betaine aldehyde: step 1/1. |
| SUBUNIT | Dimer of dimers. |
| SIMILARITY | Belongs to the aldehyde dehydrogenase family. |
