D-PSICOSE 3-EPIMERASE MUTANT WITH IMPROVED THERMAL STABILITY, AND CONTINUOUS PRODUCTION OF D-PSICOSE USING SAME
摘要
The present invention relates to a D-psicose 3-epimerase mutant of which the thermal stability is improved by substituting an amino acid of a specific sequence number. In addition, the present invention relates to a recombinant vector comprising the gene of the D-psicose 3-epimerase mutant, and a recombinant strain transformed with the recombinant vector. Further, the present invention relates to an immobilized reactor prepared using the enzyme mutant or the recombinant vector, and a method for producing D-psicose using the immobilized reactor.
