Safety evaluation of the food enzyme d-psicose 3-epimerase from the genetically modified <i>Escherichia coli</i> strain K-12 W3110-TKO CDX-088. [PDF]

EFSA J
Abstract The food enzyme d‐psicose 3‐epimerase (EC 5.1.3.30) is produced with the genetically modified Escherichia coli strain K‐12 W3110‐TKO CDX‐088 by Tate & Lyle Ingredients France SAS. The production strain of the food enzyme contains several copies of a known antimicrobial resistance gene. However, based on the absence of viable cells and DNA from

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 ...

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.

Reaction Engineering and Comparison of Electroenzymatic and Enzymatic ATP Regeneration Systems

ChemElectroChem, Volume 10, Issue 22, November 14, 2023., 2023
An electrochemically coupled ATP regeneration by pyruvate oxidase and acetate kinase for the phosphorylation of mevalonate was established and expanded by a polyphosphate kinase. The reaction was characterized and compared with other ATP regenerating systems in terms of the phosphate donor properties and biocatalytic metrics.

A multi‐level approach reveals key physiological and molecular traits in the response of two rice genotypes subjected to water deficit at the reproductive stage

Plant-Environment Interactions, Volume 4, Issue 5, Page 229-257, October 2023., 2023
Two rice genotypes were subjected to a moderate water deficit applied during the reproductive phase. Multi‐level transcriptomic, metabolomic, physiological, and morphological analyses were performed to investigate the complex traits involved in their response to drought.

Potent Inhibitory Effects of D-tagatose on the Acid Production and Water-insoluble Glucan Synthesis of Streptococcus mutans GS5 in the Presence of Sucrose [PDF]

, 2015
We examined and compared the inhibitory effects of D-tagatose on the growth, acid production, and water-insoluble glucan synthesis of GS5, a bacterial strain of Streptococcus mutans, with those of xylitol, D-psicose, L-psicose and L-tagatose.

Food manufacturing processes and technical data used in the exposure assessment of food enzymes

EFSA Journal, Volume 21, Issue 7, July 2023., 2023
Abstract Food enzymes are used for technical purposes in the production of food ingredients or foods‐as‐consumed. In the European Union, the safety of a food enzyme is evaluated by EFSA on the basis of a technical dossier provided by an applicant. Dietary exposure is an integral part of the risk assessment of food enzymes.

Crystal structure of β-d,l-psicose

Acta Crystallographica Section E: Crystallographic Communications, 2015
The title compound, C6H12O6, a C-3 position epimer of fructose, was crystallized from an aqueous solution of equimolar mixture of d- and l-psicose (1,3,4,5,6-pentahydroxyhexan-2-one, ribo-2-hexulose, allulose), and it was confirmed that d-psicose (or l ...

Possibilities of Optimizing the Purity of Mannose in Continuous Chromatographic Separation

Chemical Engineering &Technology, Volume 46, Issue 6, Page 1298-1306, June 2023., 2023
The design of continuous simulated moving‐bed chromatography and its optimization for the separation of mannose from natural sources are described. The results are compared based on the purities of mannose in the extract stream and galactose in the raffinate stream.
