A stable immobilized d-psicose 3-epimerase for the production of d-psicose in the presence of borate
Process Biochemistry, 2009Abstract 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 ...

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+).

Characterization of a d-psicose-producing enzyme, d-psicose 3-epimerase, from Clostridium sp.
Biotechnology Letters, 2013The gene coding for D-psicose 3-epimerase (DPEase) from Clostridium sp. BNL1100 was cloned and expressed in Escherichia coli. The recombinant enzyme was purified by Ni-affinity chromatography. It was a metal-dependent enzyme and required Co(2+) as optimum cofactor.

The aim of the present work was to improve stability of d-psicose 3-epimerase and biotransformation of fruit and vegetable residues for d-psicose production. The study established that N-terminal fusion of a yeast homolog of SUMO protein - Smt3 - can confer elevated optimal temperature and improved operational stability to d-psicose 3-epimerase.

Recent advances on applications and biotechnological production of d-psicose
Applied Microbiology and Biotechnology, 2012D-Psicose is a hexoketose monosaccharide sweetener, which is a C-3 epimer of D-fructose and is rarely found in nature. It has 70 % relative sweetness but 0.3 % energy of sucrose, and is suggested as an ideal sucrose substitute for food products. It shows important physiological functions, such as blood glucose suppressive effect, reactive oxygen ...
