摘要:
A method for the enzymatic preparation of amino acids of the general formula (3) or (4) from alpha-dehydroamino acids of the general formula (1) or (2) wherein R1, R2 are independently of one another H, C1-C6 alkyl, C2-C6 alkenyl, an optionally substituted carbo- or heterocyclic, aromatic or nonaromatic radical, or an alkylaryl radical, or a carboxyl radical (—COOR), R3 is H, formyl, acetyl, propionyl, benzyl, benzyloxycarbonyl, BOC, Alloc, R is H, C1-C6 alkyl, aryl, by reducing a compound of the formula (1) or (2) in the presence of a reductase.
摘要:
The invention relates to biocatalysts showing alcohol dehydrogenase activity obtainable from Rhodococcus ruber, their preparation, their use in the oxidation of secondary alcohols and/or the reduction of ketones, as well as nucleic acids coding for these alcohol dehydrogenases and microorganisms transformed with nucleic acids coding for these biocatalysts and their use for producing the biocatalyst or oxidizing secondary alcohols and/or reducing ketones.
