Protein

NAD/NADP-dependent betaine aldehyde dehydrogenase

Gene

betB

Organism
Stenotrophomonas maltophilia (strain K279a)
Status
Reviewed-Annotation score: -Protein inferred from homologyi

Functioni

Involved in the biosynthesis of the osmoprotectant glycine betaine. Catalyzes the reversible oxidation of betaine aldehyde to the corresponding acid.UniRule annotation

Catalytic activityi

Betaine aldehyde + NAD+ + H2O = betaine + NADH.UniRule annotation

Cofactori

K+UniRule annotationNote: Binds 2 potassium ions per subunit.UniRule annotation

Pathwayi: betaine biosynthesis via choline pathway

This protein is involved in step 1 of the subpathway that synthesizes betaine from betaine aldehyde.UniRule annotation
Proteins known to be involved in this subpathway in this organism are:
  1. NAD/NADP-dependent betaine aldehyde dehydrogenase (betB)
This subpathway is part of the pathway betaine biosynthesis via choline pathway, which is itself part of Amine and polyamine biosynthesis.
View all proteins of this organism that are known to be involved in the subpathway that synthesizes betaine from betaine aldehyde, the pathway betaine biosynthesis via choline pathway and in Amine and polyamine biosynthesis.
