Function
function
Involved in the biosynthesis of the osmoprotectant glycine betaine. Catalyzes the irreversible oxidation of betaine aldehyde to the corresponding acid.
Catalytic activity
- betaine aldehyde + H2O + NAD+ = glycine betaine + 2 H+ + NADHThis reaction proceeds in the forward direction.
Cofactor
Note: Binds 2 potassium ions per subunit.
Pathway
Amine and polyamine biosynthesis; betaine biosynthesis via choline pathway; betaine from betaine aldehyde: step 1/1.
