Construction of hyperthermostable d-allulose 3-epimerase from Arthrobacter globiformis M30 using the sequence information from Arthrobacter psychrolactophilus. [PDF]

FEBS Open Bio
d‐Allulose can be produced from d‐fructose by d‐allulose 3‐epimerase. Based on sequence homology information, we successfully engineered thermostable mutants with the protein engineering method. By integrating positive mutations, we constructed an enzyme that exhibits hyperthermostability without a loss in the activity.

Safety of D-allulose as a novel food pursuant to Regulation (EU) 2015/2283. [PDF]

EFSA J
Abstract Following a request from the European Commission, the EFSA Panel on Nutrition, Novel Foods and Food Allergens (NDA) was asked to deliver an opinion on D‐allulose as a novel food (NF) pursuant to Regulation (EU) 2015/2283. During the risk assessment, the Panel identified a number of data gaps, which needed to be addressed by the applicant ...

An Update: Enzymatic Synthesis for Industrial Applications. [PDF]

Angew Chem Int Ed Engl
Biocatalysis has become a sustainable and cost‐competitive alternative to established chemical synthesis, enabling the enzyme‐based production of not only commodity chemicals but (non‐natural) amino acids, (rare) sugars, as well as synthetic nucleotides.

Optimization of fermentation conditions for whole cell catalytic synthesis of D-allulose by engineering Escherichia coli [PDF]

Scientific Reports
D-allulose/D-psicose is a significant rare sugar with broad applications in the pharmaceutical, food, and other industries. In this study, we cloned the D-allulose 3-epimerase (DPEase) gene from Arthrobacter globiformis M30, using pET22b as the vector ...

Toxicological Assessment of D-Allulose From a Novel One-Step Fermentation Process Using Genetically Modified <i>Escherichia coli</i>: A 90-Day Dietary Toxicity Study in Rats. [PDF]

J Toxicol
D‐Allulose is a rare monosaccharide structurally similar to D‐fructose, characterized by low caloric content and relatively high sweetness. This study aimed to conduct a 90‐day oral toxicity test to systemically evaluate the potential toxicological effects of D‐allulose produced via a novel one‐step fermentation process using genetically engineered ...

A Novel D-Psicose 3-Epimerase from Halophilic, Anaerobic Iocasia fonsfrigidae and Its Application in Coconut Water. [PDF]

Int J Mol Sci, 2023
D-Psicose is a rare, low-calorie sugar that is found in limited quantities in national products. Recently, D-psicose has gained considerable attention due to its potential applications in the food, nutraceutical, and pharmaceutical industries. In this study, a novel D-psicose 3-epimerase (a group of ketose 3-epimerase) from an extremely halophilic ...

A Possible Mechanism of Graphene Oxide to Enhance Thermostability of D-Psicose 3-Epimerase Revealed by Molecular Dynamics Simulations. [PDF]

Int J Mol Sci, 2021
Thermal stability is a limiting factor for effective application of D-psicose 3-epimerase (DPEase) enzyme. Recently, it was reported that the thermal stability of DPEase was improved by immobilizing enzymes on graphene oxide (GO) nanoparticles. However, the detailed mechanism is not known.
