IUBMB Enzyme Nomenclature

EC 1.5.5.3

Accepted name: hydroxyproline dehydrogenase

Reaction: trans-4-hydroxy-L-proline + a quinone = (3R,5S)-3-hydroxy-1-pyrroline-5-carboxylate + a quinol

Other name(s): HYPDH; OH-POX; hydroxyproline oxidase; PRODH2 (gene name)

Systematic name: trans-4-hydroxy-L-proline:quinone oxidoreductase

Comments: A flavoprotein (FAD). The enzyme from human also has low activity with L-proline (cf. EC 1.5.5.2, proline dehydrogenase).
