In recent years, with the increasing public health awareness, low-calorie rare sugars have received more attention on a global scale. D-Allulose, the C-3 epimer of D-fructose, is a representative rare sugar. It displays high sweetness and excellent physiological functions, but only provides a caloric value of 0.4 kcal/g. D-Allulose 3-epimerase (DAEase)

D-Allulose, as low-calorie rare sugar, possessed several notable biological activities and was biosynthesized by D-allulose 3-epimerase (DAEase). Here, CcDAE from Clostridium cellulolyticum was successfully immobilization via covalent attachment (RI-CcDAE), and Resin-SpyCatcher/SpyTag-CcDAE modular (DI-CcDAE).

The combined catalysis of glucose isomerase (GI) and D-psicose 3-epimerase (DPEase) provided a convenient route for the direct synthesis of D-allulose from d-glucose, whose cost is lower than d-fructose. In the present research, the weak activity of DPEase was the key rate-limiting step and resulted in the accumulation of d-fructose in engineered ...

Recent Advances in Ketose 3-Epimerase and Its Application for D-Allulose Production
2021In the past few decades, the number of people dealing with obesity, diabetes, hyperlipidemia, and hypertension has grown dramatically throughout the world. The main reason leading to this case is the high-sugar and high-fat diets (Van Laar et al. 2020). With the continuous development of human’s living standards, the health awareness of the publics has

A novel D-allulose 3-epimerase (DAEase) from Arthrobacter psychrolactophilus (Ap DAEase) was first characterized in this study. The enzyme catalyzes the epimerization of d-fructose into a functional rare sugar, D-allulose. Ap DAEase was the first record of DAEase identified as a homotrimer with the molecular weight of its subunit at approximately 34 ...

Protein Expression and Purification, 2022
d-allulose, a rare sugar that is scarce in nature, exerts several beneficial effects and has commercial potential. d-allulose 3-epimerase (DAEase) plays a vital role in catalyzing the isomerization from d-fructose to d-allulose. However, the industrial application of DAEase for d-allulose production is hindered by its poor long-term thermostability. In

Elucidation of d-allulose recognition mechanism in ketose 3-epimerase
Journal of Bioscience and Bioengineeringd-Allulose is a low-calorie sweetener with multiple nutritional functions that can be produced through d-fructose isomerization by ketose 3-epimerase (KEase). l-Ribulose 3-epimerase from Arthrobacterglobiformis (AgLRE) is one of the most important enzymes that produce d-allulose; however, its substrate recognition mechanism is unknown.

D-allulose, a low-calorie functional sweetener, is produced by the enzymatic conversion of d-fructose via D-allulose 3-epimerase (DAE) and holds significant market potential, particularly for individuals with obesity and diabetes. However, the limited reusability and stability of DAE have restricted its industrial application.
