  • Patent number: 12600995
    Abstract: An enzyme for reducing cystine to cysteine is a fusion protein that includes the protein activities of thioredoxin (protein i) having KEGG database number EC 1.8.4.8 or EC 1.8.4.10 and thioredoxin reductase (protein ii) having KEGG database number EC 1.8.1.9. The thioredoxin (protein i) is the protein activity of thioredoxin 1 from E. coli and the thioredoxin reductase (protein ii) is the protein activity of the thioredoxin reductase from E. coli. The activity of the fusion protein is at least 100% of the activity of a mixture of the same but unfused individual proteins i and ii. The fusion protein has the enzyme activity to reduce cystine to cysteine. The coding sequences (cds) responsible for the activity of protein i and ii has been fused.

  • Patent number: 11326173
    Abstract: The present invention concerns a method of producing and enantiomerically pure alpha-ionone. Further, the invention concerns a nucleic acid that comprises a sequence that encodes a lycopene-epsilon-cyclase (EC), a lycopene-epsilon-cyclase (EC), plasmids, which encode components of the alpha-ionone biosynthesis and a microorganism that contains heterologous nucleotide sequences which encode the enzymes geranylgeranyl-diphosphate-synthase, isopentenyl-diphosphate-isomerase (IPI), phytoene desaturase-dehydrogenase (crtI), phytoene synthase (crtB), lycopene-epsilon-cyclase (EC) and carotenoid-cleavage-dioxygenase (CCD1). Further, the invention concerns a method of producing highly pure epsilon-carotene.

  • Patent number: 9012227
    Abstract: The present invention relates to a cell, which has been genetically modified relative to its wild type, so that in comparison with its wild type it is able to produce more ?-aminocarboxylic acids, more ?-aminocarboxylic acid esters or more lactams derived from ?-aminocarboxylic acids, starting from carboxylic acids or carboxylic acid esters. Furthermore, the present invention relates to a method for the production of a genetically modified cell, the cells obtainable by this method, a method for the production of ?-aminocarboxylic acids, of ?-aminocarboxylic acid esters or of lactams derived from ?-aminocarboxylic acids, the ?-aminocarboxylic acids, ?-aminocarboxylic acid esters or lactams derived from ?-aminocarboxylic acids obtainable by this method, a method for the production of polyamides based on ?-aminocarboxylic acids or based on lactams and the polyamides obtainable by this method.

  • Publication number: 20050142183
    Abstract: The present invention relates to processes for the production of mistletoe lectin polypeptides in homologous and heterologous host systems and mistletoe lectin peptides as such. Further, nucleic acid molecules are provided, which code for these mistletoe lectin polypeptides, and also pharmaceutical compositions which contain these mistletoe lectin polypeptides or mistletoe lectin nucleic acids. In order to produce the many mistletoe lectin isoenzymes contained in the natural mistletoe extract, which can trigger anti-tumorigenic and mood-brightening effects, in sufficient quantities, the present invention provides a process which makes it possible to produce mistletoe lectins in required quantities biotechnologically and at the same time to recreate the diversity of the natural mistletoe extract in mistletoe lectin isoenzymes.
