Protein existenceInferred from homology

General annotation (Comments)

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 By similarity. HAMAP-Rule MF_00750

Catalytic activity

Choline + acceptor = betaine aldehyde + reduced acceptor. HAMAP-Rule MF_00750

Betaine aldehyde + NAD+ + H2O = betaine + NADH. HAMAP-Rule MF_00750

Cofactor

FAD By similarity. HAMAP-Rule MF_00750

Pathway

Amine and polyamine biosynthesis; betaine biosynthesis via choline pathway; betaine aldehyde from choline (cytochrome c reductase route): step 1/1. HAMAP-Rule MF_00750

Sequence similarities

Belongs to the GMC oxidoreductase family.
