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 wild-type D-allulose 3-epimerase derived fromis substituted with another amino acid residue, and various uses thereof. The novel allulose epimerase variant according to the present invention has a higher conversion activity of fructose to allulose than that of the wild-type D-allulose 3-epimerase derived fromor a D-allulose epimerase variant W29K/G216S/M234I, and has excellent thermal stability especially under high temperature conditions of 60° C. or higher, thereby preventing contamination during an industrial-scale enzymatic conversion reaction for the mass production of allulose, shortening the production time, and reducing the production costs.
