    摘要: The invention relates to a method comprising the following steps: a) providing a primary alcohol of the formula HO-(CH
    2 )
    x -R
    1 , in which R
    1 is selected from the group comprising -OH, -SH, -NH
    2 , and -COOR
    2 , x is at least 3, and R
    2 is selected from the group comprising H, alkyl, and aryl, b) oxidising the primary alcohol by bringing it into contact with an NAD(P)
    + -dependent alcohol dehydrogenase, and c) bringing the oxidation product from step a) into contact with a transaminase, the NAD(P)
    + -alcohol dehydrogenase and/or the transaminase being a recombinant or an isolated enzyme. The invention also relates to a whole-cell catalyst for carrying out said method, and to the use of such a whole-cell catalyst for oxidising a primary alcohol.

    摘要: The invention relates to a method having the steps of a) providing isobutyric acid, b) bringing the isobutyric acid into contact with the combination of isobutyrate kinase and phosphotransisobutyrylase and/or isobutyryl-coenzyme A-synthetase/ligase and/or isobutyrate-coenzyme A-transferase, c) bringing the product of step a) into contact with isobutyryl-coenzyme A-dehydrogenase, d) bringing the product of step b) into contact with methacrylyl-coenzyme A-hydratase, and e) hydrolyzing the product of step d) with the formation of 3-hydroxyisobutyric acid. At least one of the enzymes is used in the form of a cell which comprises an activity of 3-hydroxyisobutyric acid dehydrogenase or a variant thereof, said activity being reduced with respect to the wild type of the cell. The invention also relates to a cell which comprises at least one enzyme of the group comprising isobutyryl-coenzyme A-synthetase/ligase, isobutyrate-coenzyme A-transferase, isobutyrate-kinase, phosphotransisobutyrylase, isobutyryl-coenzyme A-dehydrogenase, methacrylyl-coenzyme A-hydratase, and 3-hydroxisobutyryl-coenzyme A-hydrolase and which has an activity of a 3-hydroxyisobutyric acid dehydrogenase or a variant thereof, said activity being reduced with respect to the wild type of the cell. Additionally, the cell preferably has a monooxygenase, even more preferably a monooxygenase of the AlkBGT type or a variant thereof. The invention also relates to the use of such a cell for producing 3-hydroxyisobutyric acid
