Modified d-allulose-3-epimerase

Abstract

Provided is a heat-resistant D-allulose-3-epimerase. A polypeptide shown in any one of the following (1) to (3): (1) a polypeptide consisting of an amino acid sequence having one or two or more amino acid substitutions selected from the group consisting of A56E, N57H, R58G and F111W in SEQ ID NO:1; (2) a polypeptide consisting of the amino acid sequence having substitution, addition, insertion or deletion of one or several amino acid residues in the amino acid sequence described in (1) above, having D-allulose-3-epimerase activity and retaining one or two or more amino acid substitutions selected from the group consisting of A56E, N57H, R58G, and F111W; and (3) a polypeptide having a 90% or more sequence identity to the amino acid sequence described in (1) above, having D-allulose-3-epimerase activity and retaining one or two or more amino acid substitutions selected from the group consisting of A56E, N57H, R58G, and F111W.
