Transglycosylation of gallic acid by using Leuconostoc glucansucrase and its characterization as a functional cosmetic agent

AMB Express, 2017
Gallic acid glycoside was enzymatically synthesized by using dextransucrase and sucrose from gallic acid. After purification by butanol partitioning and preparative HPLC, gallic acid glucoside was detected at m/z 355 (C13, H16, O10, Na)+ by matrix ...

Expanding the Enzymatic Polymerization Landscape by Lipid Mesophase Soft Nanoconfinement

Angewandte Chemie, Volume 136, Issue 1, January 2, 2024.
The enzymatic synthesis of dextran in lipidic mesophase catalyzed by the enzyme dextransucrase DSR‐M not only yields polymers at 30 °C that are six times longer than in bulk solution at identical concentrations of reactants, but also allows the reaction to be carried out in subzero liquid water at temperatures as low as −20 °C.

Sucrose-Induced Proteomic Response and Carbohydrate Utilization of Lactobacillus sakei TMW 1.411 During Dextran Formation

Frontiers in Microbiology, 2018
Lactobacillus (L.) sakei belongs to the dominating lactic acid bacteria in indigenous meat fermentations, while diverse strains of this species have also been isolated from plant fermentations. We could recently show, that L.

Proteomic and in silico analyses of dextran synthesis influence on Leuconostoc lactis AV1n adaptation to temperature change

Frontiers in Microbiology, 2023
Leuconostoc lactis is found in vegetables, fruits, and meat and is used by the food industry in the preparation of dairy products, wines, and sugars. We have previously demonstrated that the dextransucrase of Lc.

Genomic Characterisation of Limosilactobacillus fermentum CRL2085 Unveiling Probiotic Traits for Application in Cattle Feed

Environmental Microbiology Reports, Volume 17, Issue 5, October 2025.
A comprehensive genomic and phenotypic analysis of Limosilactobacillus fermentum CRL2085 revealed key probiotic and nutritional traits supporting its safe application in cattle feed. The strain harbors genes for stress tolerance, adhesion, exopolysaccharide production, and B‐vitamin biosynthesis, and efficiently metabolizes plant‐derived carbohydrates,

Functional role and folding properties of the glucan‐binding domain of oral bacterial glucansucrase

FEBS Letters, Volume 599, Issue 16, Page 2388-2402, August 2025.
The role of the glucan‐binding domain in Streptococcus sobrinus glucansucrase was examined, focusing on its impact on enzymatic activity, dextran binding, and structural stability of deletion mutants and a circularly permuted protein. Our research revealed that glucosyl transfer efficiency is linked to cooperative interdomain folding.
