| titleOfInvention | Xylose isomerase mutant, DNA molecule encoding the enzyme, recombinant strain introduced with the DNA molecule, and uses thereof |
| abstract | The present invention relates to xylose isomerase mutants having improved catalytic activity, DNA molecules encoding the enzymes, recombinant strains containing the DNA molecules and their uses. The xylose isomerase mutant with improved catalytic activity can be obtained by mutating the amino acid residue of a specific site in the natural xylose isomerase, and the obtained xylose isomerase mutant has higher thermal stability; furthermore, the recombinant yeast containing the xylose isomerase mutant constructed by a synthetic biology method can be effectively applied to co-fermentation of C5 sugar and C6 sugar to produce ethanol, and the fermentation efficiency and the ethanol yield are remarkably improved. Therefore, the xylose isomerase mutant and the recombinant strain have wide application value in the fields of chemical industry, energy, food, medicine and the like, and can efficiently perform sugar-alcohol conversion fermentation. |
