Protein

Oxygen-dependent choline dehydrogenase

Gene

betA

Organism
Pseudomonas fluorescens (strain Pf0-1)
Status
Reviewed-Annotation score: -Protein inferred from homologyi

Functioni

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.UniRule annotation

Catalytic activityi

Choline + acceptor = betaine aldehyde + reduced acceptor.UniRule annotation
Betaine aldehyde + NAD+ + H2O = betaine + NADH.UniRule annotation
