Protein

Oxygen-dependent choline dehydrogenase

Gene
betA, b0311, JW0303
Organism
Escherichia coli (strain K12)
Status
Reviewed - Annotation score: 5 out of 5 - Experimental evidence at protein leveli

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.2 Publications

Catalytic activityi

Choline + acceptor = betaine aldehyde + reduced acceptor.1 Publication
Betaine aldehyde + NAD+ + H2O = betaine + NADH.1 Publication

Cofactori

FAD By similarity.UniRule annotation

Enzyme regulationi

Activated by high osmotic strength.1 Publication

Kineticsi

  1. KM=0.06 mM for NAD (at pH 7.5 and 37 degrees Celsius)1 Publication
  2. KM=0.13 mM for glycine betaine aldehyde (at pH 7.5 and 37 degrees Celsius)
  3. KM=0.5 mM for NADP (at pH 7.5 and 37 degrees Celsius)
  4. KM=1.5 mM for choline (at pH 7.5 and 37 degrees Celsius)
  5. KM=1.6 mM for glycine betaine aldehyde (at pH 7.5 and 37 degrees Celsius)

pH dependencei

Optimum pH is 7.5 for choline dehydrogenase and is between 7.5 and 9.5 for glycine betaine-aldehyde dehydrogenase.
