  • Fucosyltransferases and their applications
    Patent number: 9611285
    Abstract: The present invention relates to nucleic acid and amino acid sequences from Escherichia coli serogroup O126, coding for/representing a novel alpha-1,2-fucosyltransferase. The invention also provides uses and methods for using the alpha-1,2-fucosyltransferase to generate fucosylated products, such as oligosaccharides, (glyco)proteins, or (glyco)lipids, in particular oligosaccharides found in human milk, such as 2?-fucosyllactose.
    Type: Grant
    Filed: July 19, 2013
    Date of Patent: April 4, 2017
    Assignee: Jennewein Biotechnologie GmbH
    Inventors: Julia Parkot, Eric Huefner, Stefan Jennewein, Lothar Elling, Leonie Engels
  • Method for the production of fucosyllactose in bacterial cells
    Patent number: 9512433
    Abstract: The present invention relates to a cell to be stably cultured in a medium, which cell is adjusted for the production of oligosaccharides, the cell being transformed to comprise at least one nucleic acid sequence coding for an enzyme involved in oligosaccharide synthesis. In addition the cell is transformed to comprise at least one nucleic acid sequence coding for a protein of the sugar efflux transporter family, a functional homolog or derivative thereof. Further, the invention concerns a method for the production of oligosaccharides involving above cell.
