Abstract
Official abstract text for this publication.
Disclosed are nucleic acid constructs comprising coding sequences operably linked to a promoter not natively associated with the coding sequence. The coding sequences encode Pichia stipitis proteins that allow recombinant strains of Saccharomyces cerevisiae expressing the protein to grow on xylose, and allow or increase uptake of xylose by Pichia stipitis or Saccharomyces cerevisiae expressing the coding sequences. Expression of the coding sequences enhances uptake of xylose and/or glucose, allowing increased ethanol or xylitol production.
First claim
Opening claim text (preview).
We claim: 1. A nucleic acid construct comprising a first coding sequence operably linked to a first promoter not natively associated with the coding sequence, the coding sequence encoding a glucose/xylose transporter polypeptide having at least 95% amino acid identity to SEQ ID NO: 2. 2. The nucleic acid construct of claim 1 , wherein the glucose/xylose transporter polypeptide comprises SEQ ID NO: 2. 3. The nucleic acid construct of claim 1…
