Production of d -psicose from d -glucose by co-expression of d -psicose 3-epimerase and xylose isomerase

Enzyme and Microbial Technology, 2017
d-Psicose has been drawing increasing attention in recent years because of its medical and health applications. The production of d-psicose from d-glucose requires the co-expression and synergistic action of xylose isomerase and d-psicose 3-epimerase.

A stable immobilized d-psicose 3-epimerase for the production of d-psicose in the presence of borate

Process Biochemistry, 2009
Abstract Maximal activity of the immobilized d -psicose 3-epimerase from Agrobacterium tumefaciens on Duolite A568 beads was achieved at pH 9.0 and 55 °C with borate, and at pH 8.5 and 50 °C without borate. The half-lives of the immobilized enzyme at 50 °C with and without borate were increased 4.2- and 128-fold compared to that of the free enzyme ...

Overexpression of d-psicose 3-epimerase from Ruminococcus sp. in Escherichia coli and its potential application in d-psicose production

Biotechnology Letters, 2012
The D-psicose 3-epimerase (DPE) gene from Ruminococcus sp. was cloned and overexpressed in Escherichia coli. The recombinant protein was purified and characterized. It was optimally active at pH 7.5-8.0 and 60 °C. Activity was not dependent on the presence of metal ions; however, it became more thermostable with added Mn(2+).

Co-expression of d-glucose isomerase and d-psicose 3-epimerase: Development of an efficient one-step production of d-psicose

Enzyme and Microbial Technology, 2014
D-Psicose has been attracting attention in recent years because of its alimentary activities and is used as an ingredient in a range of foods and dietary supplements. To develop a one-step enzymatic process of D-psicose production, thermoactive D-glucose isomerase and the D-psicose 3-epimerase obtained from Bacillus sp.
