Abstract: The present invention provides a novel promoter variant in which some nucleotides of the glyceraldehyde-3-phosphate dehydrogenase (gapA) gene promoter of Escherichia coli are deleted. The novel promoter variant according to the present invention can constitutively express a target protein at a high level, particularly an enzyme, in Escherichia coli. Therefore, a target protein, particularly an enzyme, can be economically mass-produced using a recombinant strain transformed with an expression vector containing the novel promoter variant according to the present invention. For example, allulose epimerase can be economically mass-produced or allulose can be economically mass-produced from fructose using a recombinant strain transformed with an expression vector containing the novel promoter variant according to the present invention.

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 from Flavonifractor plautii or 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.
