Reaction Steps

The cells, the treated cells or the enzyme preparation are added to 240 mM MES [2-(N-morphorino) ethanesulfonic acid] buffer containing 12 mM L-proline, 24 mM 2-ketoglutaric acid, 4 mM ferrous sulfate and 8 mM L-ascorbic acid to make 250 μl in total. The mixture is kept at 35° C. for 10 minutes. The reaction mixture is heated at 100° C. for 2 minutes to stop the reaction, and the amount of trans-4-hydroxy-L-proline produced in the reaction mixture is determined by HPLC.
