NiceZyme View of ENZYME: EC 1.1.3.17

Official Name
Choline oxidase.
Reaction catalysed
Choline + 2 O(2) + H(2)O <=> betaine + 2 H(2)O(2)
Cofactor(s)
FAD.
Comment(s)
  • 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 1.14.15.7, whereas in animals and many bacteria, it is catalyzed by either EC 1.1.99.1 or EC 1.1.3.17.
  • The enzyme involved in the second step, EC 1.2.1.8, appears to be the same in those plants, animals and bacteria that use two separate enzymes.
