    摘要： A process for the enzymatic reduction of an enoate (1) wherein the C═C bond of the enoate (1) is stereoselectively hydrogenated in the presence of an enoate-reductase and an oxidizable co-substrate (2) in a system which is free of NAD(P)H, in which A is a ketone radical (—CRO), an aldehyde radical (—CHO), a carboxyl radical (—COOR), with R═H or optionally substituted C1-C6-alkyl radical, R1, R2 and R3 are independently of one another H, —O—C1-C6-alkyl, —O—W with W=a hydroxyl protecting group, C1-C6-alkyl, which can be substituted, C2-C6-alkenyl, carboxyl, or an optionally substituted carbo- or heterocyclic, aromatic or nonaromatic radical, or one of R1, R2 and R3 is a —OH radical, or R1 is linked to R3 so as to become part of a 4-8-membered cycle, or R1 is linked to R so as to become part of a 4-8-membered cycle, with the proviso that R1, R2 and R3 may not be identical.

    摘要： The present Invention relates to new nitrilases with modified Substrate acceptance, the method to obtain them and the use of the aforesaid nitrilases. Said nitrilases are encoded by a polypeptide sequence, which at a Position corresponding to Position 296 in wild-type Alcaligenes faecalis comprises an amino acid which is not tyrosine. The Invention further relates to nucleic acid sequences and amino acid sequences encoding Said nitrilases, expression constructs comprising Said nucleic acid sequences, vectors comprising the nucleic acid sequences or the exPression constructs, to organisms, preferably microorganisms, comprising the nucleic acid sequences, expression constructs or vectors. The Invention additionally relates to a method for preparing carboxylic acids, preferably substituted chiral carboxylic acids from racemic nitriles.
