CC -!- FUNCTION: Involved in the biosynthesis of the osmoprotectant glycine CC betaine. Catalyzes the irreversible oxidation of betaine aldehyde to CC the corresponding acid. {ECO:0000255|HAMAP-Rule:MF_00804}. CC -!- CATALYTIC ACTIVITY: CC Reaction=betaine aldehyde + NAD(+) + H2O = glycine betaine + NADH + 2 CC H(+); Xref=Rhea:RHEA:15305, ChEBI:CHEBI:15377, ChEBI:CHEBI:15378, CC ChEBI:CHEBI:15710, ChEBI:CHEBI:17750, ChEBI:CHEBI:57540, CC ChEBI:CHEBI:57945; EC=1.2.1.8; Evidence={ECO:0000255|HAMAP- CC Rule:MF_00804}; CC PhysiologicalDirection=left-to-right; Xref=Rhea:RHEA:15306; CC Evidence={ECO:0000255|HAMAP-Rule:MF_00804}; CC -!- COFACTOR: CC Name=K(+); Xref=ChEBI:CHEBI:29103; Evidence={ECO:0000255|HAMAP- CC Rule:MF_00804}; CC Note=Binds 2 potassium ions per subunit. {ECO:0000255|HAMAP- CC Rule:MF_00804}; CC -!- PATHWAY: Amine and polyamine biosynthesis; betaine biosynthesis via CC choline pathway; betaine from betaine aldehyde: step 1/1. CC {ECO:0000255|HAMAP-Rule:MF_00804}. CC -!- SUBUNIT: Dimer of dimers. {ECO:0000255|HAMAP-Rule:MF_00804}. CC -!- SIMILARITY: Belongs to the aldehyde dehydrogenase family.
