4-Morpholineethanesulfonic acid → L-Hydroxyproline

Participants

Reaction Steps

The enzyme reaction with purified L-proline-4-hydroxylase obtained in Example 5 was carried out. The reaction mixture was composed of 200 mM MES buffer (pH 6.5), 20 mM L-proline, 20 mM 2-ketoglutarate, 5 mM L-ascorbic acid, 2 mM ferrous sulfates and 90 U of purified enzyme preparation in total volume of 50 μl. The reaction was carried out at 35° C. for 30 min. As a result of the reaction, 12.9 mM (1.7 g/1) of trans-4-hydroxyL-proline was produced in the reaction mixture.
