Highly efficient production of Clostridium cellulolyticum H10 d-psicose 3-epimerase in Bacillus subtilis and use of these cells to produce d-psicose [PDF]

Microbial Cell Factories, 2018
Background d-Psicose 3-epimerase (DPEase) catalyzes the isomerization of d-fructose to the rare sugar d-psicose, which may help prevent obesity, reduce blood sugar and blood fat, and inhibit intra-abdominal fat accumulation.

Streamlined production of immobilized D-psicose 3-epimerase via secretion in Pichia pastoris: a new paradigm for industrial D-psicose production [PDF]

Microbial Cell Factories
Background D-psicose, a rare sugar with significant health benefits, holds great promise as a low-calorie sweetener. Its synthesis requires the enzyme called D-psicose 3-epimerase (DPEase), which converts D-fructose into D-psicose.

The Study on Long-Term Toxicity of D-Psicose in Rats [PDF]

Journal of Clinical Biochemistry and Nutrition, 2009
D-Psicose is a rare sugar present in small quantities in natural products. In a previous study, we showed that D-psicose suppresses plasma glucose increases and reduces body fat accumulation in rats. Based on acute toxicity testing in rats, D-psicose is classified as an ordinary substance (LD(50) = 16 g/kg). Elucidating the effects of long term feeding

D-Allulose (D-Psicose) Biotransformation From Allitol by a Newly Found NAD(P)-Dependent Alcohol Dehydrogenase From Gluconobacter frateurii NBRC 3264 and the Enzyme Characterization [PDF]

Frontiers in Microbiology, 2022
The NAD(P)-dependent alcohol dehydrogenase (ADH) gene was cloned from Gluconobacter frateurii NBRC 3264 and expressed in Escherichia coli BL21 star (DE3). The expressed enzyme was purified and the characteristics were investigated.
