| titleOfInvention | Pyruvate decarboxylase mutant with improved enzyme activity |
| abstract | The invention discloses a pyruvate decarboxylase mutant with improved enzyme activity, belonging to the field of enzyme engineering and bioengineering. According to the invention, through a site-directed mutagenesis method, hydrophilic amino acid valine in a region with poor stability in a pyruvate decarboxylase molecule is mutated into tyrosine with stronger hydrophobicity, the hydrophobicity in the enzyme molecule is changed, the enzyme activity of the pyruvate decarboxylase is improved, and the yield of xylose is improved in a reaction of catalyzing 2-keto-L-gulonic acid to generate L-xylose. The modified enzyme is more suitable for industrial application in the production of producing L-xylose, can reduce the production cost and improve the production efficiency. |
