Protein

Oxygen-dependent choline dehydrogenase

Gene

betA

Organism
Acinetobacter baumannii (strain SDF)
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

Pathwayi: betaine biosynthesis via choline pathway

This protein is involved in step 1 of the subpathway that synthesizes betaine aldehyde from choline (cytochrome c reductase route).UniRule annotation
Proteins known to be involved in this subpathway in this organism are:
  1. Oxygen-dependent choline dehydrogenase (betA)
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 aldehyde from choline (cytochrome c reductase route), the pathway betaine biosynthesis via choline pathway and in Amine and polyamine biosynthesis.
