PROTEIN, DNA MOLECULE, GENETICALLY MODIFIED Yeast EUCHARIOTIC CELLS, USES OF PROTEIN, DNA MOLECLE AND EUCHARIOTIC CELLS AND ETHANOL PRODUCTION PROCESSES AND FERMENTATION PRODUCT GENERATION PROCESSES

摘要

protein, dna molecule, eukaryotic cells and genetically modified yeast, uses of protein, dna molecule and eukaryotic cells and processes for ethanol production and fermentation product generation the present invention provides a microbial eukaryotic cell capable of using c5 sugars, particularly xylose. another objective of the present invention is to provide an enhanced protein sequence to allow eukaryotic cells to break down c5 sugars. the present invention therefore provides proteins that comprise an amino acid sequence that has at least 75% identity, preferably 80% identity, more preferably 90% identity and, preferably higher, 95% identity with sequence n ° 2 or seq id # 8 and has xylose isomerase activity in eukaryotic cells.
