Abstract
The present invention provides a novel allulose epimerase variant and various uses thereof, in which glycine (Gly), an amino acid residue at position 216 of the amino acid sequence of wild-type D-allulose 3-epimerase derived from, is substituted with serine (Ser). The novel allulose epimerase variant according to the present invention has a higher conversion activity of fructose to allulose compared to the wild-type D-allulose 3-epimerase derived from, and in particular, it has excellent thermal stability under high temperature conditions of 60° C. or higher, so that the enzyme conversion reaction is performed at the industrial level for mass production of allulose to prevent contamination, to shorten production time, and to reduce production cost.
