In enzymology, 4-oxoproline reductase (EC 1.1.1.104) is an enzyme that catalyzes the chemical reaction
The substrates of this enzyme are cis-4-hydroxyproline, and oxidised nicotinamide adenine dinucleotide (NAD+). Its products are 4-oxo-L-proline and reduced NADH. [1] [2] [3]
This enzyme belongs to the family of oxidoreductases, specifically those acting on the CH-OH group of donor with NAD+ or NADP+ as acceptor. The systematic name of this enzyme class is 4-hydroxy-L-proline:NAD+ oxidoreductase. This enzyme is also called hydroxy-L-proline oxidase. This enzyme was originally thought to participate in the metabolism of arginine and proline. However, recent data show that it is unlikely since neither 4-oxo-L-proline nor cis-4-hydroxy-L-proline are metabolites of these metabolic pathways.
