ABSTRACT:
Provided is a method of producing D-psicose using a D-psicose epimerase derived fromAgrobacterium tumefaciens. Provided are a protein having an amino acid sequence of SEQ ID NO:1 and having a psicose 3-epimerase activity, a gene encoding the protein, a recombinant expression vector containing the gene, and a method of producing D-psicose by reacting the protein produced on a mass scale with D-fructose. The method of producing D-psicose is an environmentally friendly method using a new enzyme, in which an inexpensive substrate is used, and the activity of the enzyme can be retained for a prolonged time period. Thus, the method can be efficiently used for the mass production of D-psicose.
