Abstract
The present invention relates to a D-psicose 3-epimerase variant with improved thermostability by substituting an amino acid at a specific position of an amino acid sequence of a wild type D-psicose 3-epimerase. Further, the present invention provides a recombinant expression vector including a gene of the D-psicose 3-epimerase variant, and a recombinant strain transformed with the recombinant expression vector. Furthermore, the present invention provides an immobilized reactor prepared using the D-psicose 3-epimerase variant or the recombinant strain, and a method of continuously producing D-psicose using the immobilized reactor.
