EC 1.1.1.104

Accepted name: 4-oxoproline reductase

Reaction: cis-4-hydroxy-L-proline + NAD+ = 4-oxo-L-proline + NADH + H+

Other name(s): cis-hydroxy-L-proline oxidase

Systematic name: cis-4-hydroxy-L-proline:NAD+ oxidoreductase (4-oxo-L-proline forming)

Comments: The enzyme, isolated from animals, is specific for 4-oxo-L-proline and cis-4-hydroxy-L-proline. It has no activity with trans-4-hydroxy-L-proline.
