Allulose 3-epimerase mutant, engineered bacterium expressing same, and immobilized enzyme and immobilization method thereof |
| abstract |
Provided are an allulose 3-epimerase mutant and a genetically engineered bacterium expressing the mutant. Further provided are an immobilized allulose 3-epimerase enzyme and an immobilization method thereof . A high-throughput screening method is used to obtain an allulose 3-epimerase mutant efficiently expressed in a fermentation process, which can catalyze efficient conversion of fructose to D-allulose, providing an efficient production path for key enzymes required in a D-allulose production process. Additionally, the allulose 3-epimerase is bonded to an immobilizing resin to prepare an immobilized allulose 3-epimerase enzyme. The immobilized enzyme can be applied to batch or continuous reactions to catalyze efficient conversion of fructose to D-allulose, improves the reuse rate and use life of the enzyme, can significantly reduce the production costs of D-allulose, and can be widely applied. |
