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.

Publisher Summary This chapter discusses the preparation of psicose, sorbose, and tagatose. It also discusses the D- and L-isomers of these ketohexoses. When Lobry de Bruyn and Van Ekenstein studied the transformations of reducing sugars in aqueous alkaline solution, they interpreted their experimental results in terms of the Fischer configurational ...

L-Psicose has been obtained by hydrolysis of the product of the stereoselective reduction of methyl 1,3-O-benzylidene-5-O-p-tolylsulphonyl-α-L-erythro-hexo-2,4-diulopyranoside.
