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; 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.
CC       {ECO:0000255|HAMAP-Rule:MF_00804}.
