  • Patent number: 9719117
    Abstract: The invention provides a whole cell catalyst which expresses a recombinant ?-dioxygenase or the combination of a recombinant fatty acid reductase and a phosphopantetheinyl transferase phosphopantetheinylating the fatty acid reductase, and which in addition to the ?-dioxygenase and/or the combination of fatty acid reductase and phosphopantetheinyl transferase expresses a transaminase, characterized in that the phosphopantetheinyl transferase and/or transaminase is preferably recombinant; and a method for the conversion of a fatty acid, ?-hydroxy fatty acid, ?-oxo fatty acid or a monoester thereof to an amine, comprising oxidation of the fatty acid, ?-hydroxy fatty acid, ?-oxo fatty acid or the monoester thereof to an oxidation product by contacting with an alkane hydroxylase and/or alcohol dehydrogenase, contacting the oxidation product with a phosphopantetheinylated fatty acid reductase or a ?-dioxygenase to give an aldehyde, and contacting the aldehyde with a transaminase.
    Type: Grant

  • Patent number: 9249435
    Abstract: A process for the improved separation of a hydrophobic organic solution from an aqueous culture medium is provided. The process includes preparing an aqueous culture medium of a metabolically active cell having a decreased activity; contacting of the aqueous culture medium with a hydrophobic organic solution comprising a substrate for biotransformation; conducting a biotransformation of the substrate; and separating the hydrophobic organic solution comprising a biotransformed substrate from the aqueous culture medium. The decreased activity of the metabolically active cell is in comparison to a wild-type of the active cell and the decreased activity is of at least of one enzyme that catalyzes one reaction of ?-oxidation of fatty acids.

  • Publication number: 20150307906
    Abstract: The invention relates to a whole-cell catalyst which expresses a recombinant ?-dioxygenase or the combination of a recombinant fatty acid reductase and a phosphopantetheinyl transferase which phosphopantetheinylates the fatty acid reductase, and which expresses, in addition to the ?-dioxygenase and/or the combination of fatty acid reductase and phosphopantetheinyl transferase, a transaminase, wherein the phosphopantetheinyl transferase and/or transaminase is preferably recombinant; and also to a process for converting a carboxylic acid or dicarboxylic acid or a monoester thereof to an amine or diamine, comprising the steps of contacting the carboxylic acid or dicarboxylic acid or the monoester thereof with a phosphopantetheinylated fatty acid reductase or an ?-dioxygenase and contacting the product with a transaminase.
