Structural determinants of alternating (α1 → 4) and (α1 → 6) linkage specificity in reuteransucrase of Lactobacillus reuteri
Xiangfeng Meng,Tjaard Pijning,Justyna M. Dobruchowska,Huifang Yin,Gerrit J. Gerwig,Lubbert Dijkhuizen +5 more
TL;DR: It is shown that residues in loop977 (970DGKGYKGA977) and helix α4 (1083VSLKGA1088) are main determinants for the linkage specificity difference between GTFO and GTFA, and hence are important for the synthesis of alternating linkages in GTFA.
Synthesis of oligo- and polysaccharides by Lactobacillus reuteri 121 reuteransucrase at high concentrations of sucrose.
Xiangfeng Meng,Justyna M. Dobruchowska,Gerrit J. Gerwig,Johannis P. Kamerling,Lubbert Dijkhuizen +4 more
TL;DR: The finding of an additional branched hexasaccharide demonstrates that the enzyme is able to introduce branch-points already in relatively short oligosaccharides, suggesting that the size distribution of products is kinetically controlled, but the linkage distribution in the polysaccharide material is not changed.
Cell wall polysaccharides of Chinese Wolfberry (Lycium barbarum): Part 2. Characterisation of arabinogalactan-proteins
Robert J. Redgwell,Delphine Curti,Juankuan Wang,Justyna M. Dobruchowska,Gerrit J. Gerwig,Johannis P. Kamerling,Peter Bucheli +6 more
TL;DR: In this article, a backbone of (1 − 3)-linked beta-D-galactopyranosyl residues was found in the Wolfberry AGP, with side chains of 5-substituted alpha-L-arabinofuranosyl residue.
Structural basis for the roles of starch and sucrose in homo-exopolysaccharide formation by Lactobacillus reuteri 35-5.
Yuxiang Bai,Justyna M. Dobruchowska,Rachel M. van der Kaaij,Gerrit J. Gerwig,Lubbert Dijkhuizen +4 more
TL;DR: The data show that both in vivo and in vitro the L. reuteri 35-5 GS and 4,6-α-GTase enzymes, incubated with sucrose plus starch, cross-react and contribute to synthesis of the final hybrid EPS products.
Biocatalytic refining of polysaccharides from brown seaweeds

TL;DR: The main constituent polysaccharides, being alginate, cellulose, laminaran, and fucoidan, are the components of greatest importance for biorefinery usage.
