Abstract
The present invention provides: a novel allulose epimerase variant in which an amino acid residue present at a specific position of an amino acid sequence of a wild-type D-allulose 3-epimerase derived fromis substituted with another amino acid residue; and various uses of the novel allulose epimerase variant. The novel allulose epimerase variant according to the present invention has a higher conversion rate of fructose to allulose compared to that of the wild-type D-allulose 3-epimerase derived from, and has excellent thermal stability especially under high temperature conditions of 60° C. or higher, and thus can prevent contamination during an industrial-scale enzymatic conversion reaction for the mass production of allulose, shorten production time, and reduce production costs.
