1. A recombinant nucleic acid construct comprising at least one polynucleotide sequence that encodes a polypeptide which is capable of catalyzing the isomerization of D-xylose directly to D-xylulose, wherein the polynucleotide is a polynucleotide that encodes a polypeptide comprising an amino acid sequence having at least 70%, at least 75%, at least 80%, at least 85%, at least 90%, or at least 95% identity to SEQ ID NO:23; 25, 27, 29, 31, and/ or 33, or a polynucleotide that hybridizes under stringent hybridization conditions to the complement of a polynucleotide that encodes a polypeptide having the amino acid sequence of SEQ ID NO: 23; 25, 27, 29, 31, and/ or 33. |
