FUNCTION | Involved in the biosynthesis of the osmoprotectant glycine betaine. Catalyzes the oxidation of choline to betaine aldehyde and betaine aldehyde to glycine betaine at the same rate. |
CATALYTIC ACTIVITY | Reaction=A + choline = AH2 + betaine aldehyde; Xref=Rhea:RHEA:17433, ChEBI:CHEBI:13193, ChEBI:CHEBI:15354, ChEBI:CHEBI:15710, ChEBI:CHEBI:17499; EC=1.1.99.1; |
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; |
COFACTOR | Name=FAD; Xref=ChEBI:CHEBI:57692; |
PATHWAY | Amine and polyamine biosynthesis; betaine biosynthesis via choline pathway; betaine aldehyde from choline (cytochrome c reductase route): step 1/1. |
SIMILARITY | Belongs to the GMC oxidoreductase family. |
