General annotation (Comments)

Function

Involved in the biosynthesis of the osmoprotectant glycine betaine. Catalyzes the reversible oxidation of betaine aldehyde to the corresponding acid By similarity. HAMAP-Rule MF_00804

Catalytic activity

Betaine aldehyde + NAD+ + H2O = betaine + NADH. HAMAP-Rule MF_00804

Cofactor

Binds 2 potassium ions per subunit By similarity. HAMAP-Rule MF_00804

Pathway

Amine and polyamine biosynthesis; betaine biosynthesis via choline pathway; betaine from betaine aldehyde: step 1/1. HAMAP-Rule MF_00804

Subunit structure

Dimer of dimers By similarity. HAMAP-Rule MF_00804

Sequence similarities

Belongs to the aldehyde dehydrogenase family.
