Reaction Steps

Improved ADH-LK variants for the reduction of (S)-1-(4-Fluoro-phenyl)-5-(2-oxo-4-phenyl-oxazolidin-3-yl)-pentane-1,5-dione to (4S)-3-[(5S)-5-(4-Fluoro-phenyl)-5-hydroxy-pentanoyl]-4-phenyl-oxazolidin-2-one were analyzed in small scale chemical reactions. In a glass vial with a teflon stirring bar, 500 mg (S)-1-(4-Fluoro-phenyl)-5-(2-oxo-4-phenyl-oxazolidin-3-yl)-pentane-1,5-dione, 100 mg KRED variant, 0.5 mg Na-NADP (Oriental Yeast), 2.5 ml isopropyl alcohol, and 2.5 ml 100 mM triethanolamine(chloride) buffer, pH 7.0, 2 mM MgSO4 was mixed and stirred overnight at 25° C. Reaction samples were analyzed by the method of Example 4.
