ENZYME entry: EC

Accepted Name
Choline monooxygenase.
Reaction catalysed
Choline + O(2) + 2 reduced ferredoxin + 2 H(+) <=> betaine aldehyde hydrate + H(2)O + 2 oxidized ferredoxin
Iron-sulfur; Mg(2+).
  • Catalyzes the first step of glycine betaine synthesis.
  • In many bacteria, plants and animals, the osmoprotectant betaine is synthesized in two steps: (1) choline to betaine aldehyde and (2) betaine aldehyde to betaine.
  • Different enzymes are involved in the first reaction.
  • In plants, the reaction is catalyzed by this enzyme whereas in animals and many bacteria, it is catalyzed by either membrane-bound EC or soluble EC
  • The enzyme involved in the second step, EC, appears to be the same in plants, animals and bacteria.
  • In some bacteria, betaine is synthesized from glycine through the actions of EC and EC
  • Formerly EC
