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 + H2O + NAD(+) = glycine betaine + 2 H(+) +
CC NADH; Xref=Rhea:RHEA:15305, ChEBI:CHEBI:15377, ChEBI:CHEBI:15378,

CC Evidence={ECO:0000255|HAMAP-Rule:MF_00804};
CC -!- COFACTOR:
CC Name=K(+); Xref=ChEBI:CHEBI:29103;
CC Evidence={ECO:0000255|HAMAP-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.
CC {ECO:0000255|HAMAP-Rule:MF_00804}.
