Combinatorial engineering of dextransucrase specificity. [PDF]
PLoS ONE, 2013 We used combinatorial engineering to investigate the relationships between structure and linkage specificity of the dextransucrase DSR-S from Leuconostoc mesenteroides NRRL B-512F, and to generate variants with altered specificity.

Comparative study of rebaudioside A and rebaudioside Aα: physicochemical properties and in vivo metabolism [PDF]
npj Science of FoodStevioside (ST) and rebaudioside A (Reb A) are 250 times sweeter than sucrose, but their bitterness and low water solubility limit their application. Rebaudioside Aα (Reb Aα) was synthesized using dextransucrase.

pH dependent effects of sodium ions on dextransucrase activity in Streptococcus mutans [PDF]
Biochemistry and Biophysics Reports, 2019 Dextransuccrase (E.C 2.4.1.5) is a key enzyme in S. mutans for the metabolism of sucrose which helps in the adherence and accumulation of bacteria on tooth surface leading to the formation of dental caries.

Dextransucrase: Acceptor substrate reactions
Archives of Biochemistry and Biophysics, 1981 Abstract Studies were carried out on the acceptor specificity of dextransucrase which had been isolated from Streptococcus sanguis 10558. Radioactive acceptors were employed in reactions with cold sucrose and the counts incorporated were taken as a measure of “acceptor activity.” An order of relative activity was found to be polysaccharide ...

Regulation of Sugar Metabolism During Fermentation of Brewers' Spent Grain by Leuconostoc pseudomesenteroides DSM20193. [PDF]
Microb BiotechnolThis study reveals the regulatory mechanism behind sugar metabolism and dextran synthesis by Leuconostoc pseudomesenteroides DSM20193 during the fermentation of a complex substrate like brewers spent grain. Understanding metabolic pathways and genetic adaptation of lactic acid bacteria in food environments can help develop fermented products with ...

THE JOURNAL OF VITAMINOLOGY, 1965 1. Cell-free extracts prepared from strains of Leuc. mesenteroides grown on sucrose were found to reveal the production of riboflavinylglucoside from sucrose and riboflavin. Moreover, it was found that the extract utilized only sucrose as a glucosyl donor in the formation of riboflavinylglucoside, while glucose itself was quite ineffective.2.
