D-Psicose 3-epimerase (Dpe) from Clostridium cellulolyticum

This part is an E. coli codon optimized version of the D-Psicose 3-epimerase (Dpe) from Clostridium cellulolyticum str. ATCC 35319 (Uniprot B8I944).

Usage and Biology

D-Psicose 3-epimerase (EC: 5.1.3.30) catalyses the reversible epimerization of D-fructose into D-psicose, D-psicose being the carbon-3 (C3) epimer of D-fructose.

The C. cellulolyticum Dpe is a 33.034 kDa protein of 293 amino acids.

This enzyme is highly specific for D-psicose, but it is also able to catalyse with very low activity the epimerization of D-tagatose [1]. For optimal activity, it requires cofactors such as Mn2+ or Co2+, although it has a low basal activity without ions. The native Dpe shows a tetrameric arrangement of 132 kDa, and each subunit has 293 amino acids with a molecular weight of 33 kDa. The topology of each subunit is a TIM-barrel fold with a cluster of eight β-strands surrounded by twelve α-helices [2].
