ENZYME entry: EC 1.5.5.2

Accepted Name
Proline dehydrogenase.
Reaction catalysed
L-proline + a quinone <=> (S)-1-pyrroline-5-carboxylate + a quinol
Cofactor(s)
FAD.
Comment(s)
  • The electrons from L-proline are transferred to the FAD cofactor, and from there to a quinone acceptor.
  • In many organisms, ranging from bacteria to mammals, proline is oxidized to glutamate in a two-step process involving this enzyme and EC 1.2.1.88.
  • Both activities are carried out by the same enzyme in enterobacteria.
  • Formerly EC 1.5.99.8.
