  • Publication number: 20140024820
    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.

  • Publication number: 20120135467
    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.

  • Patent number: 7402417
    Abstract: This disclosure provides the nucleic acid and protein sequences of novel P450 oxygenases that utilize, at least, taxoid substrates, including taxadiene isomers. The disclosed oxygenases, such as a taxoid 5?-hydroxylase, hydroxylate, at least, the C5 position of a taxoid. Also provided are methods of introducing oxygen at the C5 position of a taxoid and methods of producing the anti-cancer drug, paclitaxel (also known as Taxol™), and other taxoids, such as paclitaxel intermediates.
