摘要: The present invention provides a method for enzymatically producing optically active mandelic acid derivatives. An optically active mandelic acid derivative (shown as Formula II) is produced by reacting a culture or cell body of a microorganism, or processed products thereof, with a phenylglyoxylic acid derivative, and then recovering the obtained optically active mandelic acid derivative, wherein the microorganism has the ability to stereo-selectively reduce the phenylglyoxylic acid derivative. An optically active mandelic acid obtained according to the present invention is useful as an intermediate for the synthesis of pharmaceuticals and agricultural chemicals.

摘要: One chiral form of a 1-aryl-2-aminopropane is produced in preference to its enantiomer by allowing a 1-arylpropan-2-one to react with a 1-amino-1-phenylethane of predominantly one chiral form and reducing the resultant 1-(1-arylprop-2-ylideneimino)-1-phenylethane to yield phenylethane and a mixture of 1-aryl-2-aminopropanes in which one chiral form thereof is present in preference to its enantiomer. The mixture of 1-aryl-2-aminopropanes then is subjected to the action of an omega-amino acid transaminase which converts one of the two chiral forms of 1-aryl-2-aminopropane into the corresponding arylpropanone which can be separated from the remaining chiral form of the 1-aryl-2-aminopropane.

摘要: The invention relates to NAD(P)H-dependent nitrate reductase from yeasts, to a process for the preparation thereof and to the use thereof in a reagent for determining nitrate. The nitrate reductase is characterized by a molecular weight of about 350 000 D and can be obtained by yeast cells which have been cultivated in a completely synthetic nutrient medium with nitrate as the sole nitrogen source and which contain nitrate reductase being disrupted in phosphate buffer, the crude extract being chromatographed on an anion exchanger, the fractions containing nitrate reductase being mixed with protein, concentrated by ultrafiltration and dried by fluidized bed granulation. The reagent for determining nitrate contains, besides the nitrate reductase prepared in this way, also NAD(P)H and a color reagent for determining nitrite.
