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.

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 ...

Solvent effects on catalytic activity and selectivity in amine-catalyzed D-fructose isomerization [PDF]

, 2022
Rational catalyst design and optimal solvent selection are key to advancing biorefining. Here, we explored the organocatalytic isomerization of D-fructose to a valuable rare monosaccharide, D-allulose, as a function of solvent.

The Engineering, Expression, and Immobilization of Epimerases for <i>D</i>-allulose Production. [PDF]

Int J Mol Sci, 2023
The rare sugar D-allulose is a potential replacement for sucrose with a wide range of health benefits. Conventional production involves the employment of the Izumoring strategy, which utilises D-allulose 3-epimerase (DAEase) or D-psicose 3-epimerase (DPEase) to convert D-fructose into D-allulose.
