CC   -!- FUNCTION: Involved in the biosynthesis of the osmoprotectant glycine
CC       betaine. Catalyzes the oxidation of choline to betaine aldehyde and
CC       betaine aldehyde to glycine betaine at the same rate.
CC       {ECO:0000255|HAMAP-Rule:MF_00750}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=A + choline = AH2 + betaine aldehyde; Xref=Rhea:RHEA:17433,
CC         ChEBI:CHEBI:13193, ChEBI:CHEBI:15354, ChEBI:CHEBI:15710,

CC         Rule:MF_00750};
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         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_00750};
CC   -!- COFACTOR:
CC       Name=FAD; Xref=ChEBI:CHEBI:57692;
CC         Evidence={ECO:0000255|HAMAP-Rule:MF_00750};
CC   -!- PATHWAY: Amine and polyamine biosynthesis; betaine biosynthesis via
CC       choline pathway; betaine aldehyde from choline (cytochrome c reductase
CC       route): step 1/1. {ECO:0000255|HAMAP-Rule:MF_00750}.
CC   -!- SIMILARITY: Belongs to the GMC oxidoreductase family.
CC       {ECO:0000255|HAMAP-Rule:MF_00750}.
