ENZYME entry: EC

Accepted Name
Choline oxidase.
Reaction catalysed
Choline + 2 O(2) + H(2)O <=> betaine + 2 H(2)O(2)
  • In many bacteria, plants and animals, the osmoprotectant betaine is synthesized using different enzymes to catalyze the conversion of (1) choline into betaine aldehyde and (2) betaine aldehyde into betaine.
  • In plants, the first reaction is catalyzed by EC, whereas in animals and many bacteria, it is catalyzed by either EC or EC
  • The enzyme involved in the second step, EC, appears to be the same in those plants, animals and bacteria that use two separate enzymes.
