Automated Docking of α-(1,4)- and α-(1,6)-Linked Glucosyl Trisaccharides in the Glucoamylase Active Site [PDF]

open access: yes, 1998
Low-energy conformers of five α-(1,4)- and α-(1,6)-linked glucosyl trisaccharides were flexibly docked into the glucoamylase active site using AutoDock 2.2.

Spatially resolved metabolomics reveals variety-specific metabolic changes in banana pulp during postharvest senescence

open access: yesFood Chemistry: X, 2022
Banana is one of most popular fruits globally due to health-promoting and disease-preventing effects, yet little is known about in situ metabolic changes across banana varieties.

Effects of monovalent cations (Na+ and K+) on galacto-oligosaccharides production during lactose hydrolysis by kluyveromyces lactis β-galactosidase [PDF]

open access: yes, 2014
The influence of cations, Na+ and K+ on the oligosaccharides produced in the process of transglycosylation during the hydrolysis of lactose using β-galactosidase from Kluyveromyces (K.) lactis has been investigated. The enzyme exhibited higher hydrolytic

Investigation of the Protective Effect for GcMAF by a Glycosidase Inhibitor and the Glycan Structure of Gc Protein

open access: yesMolecules, 2023
O-linked α-N-acetylgalactosamine (α-GalNAc) in the Gc protein is essential for macrophage activation; thus, the GalNAc-attached form of Gc protein is called Gc macrophage activating factor (GcMAF). O-linked glycans in Gc proteins from human plasma mainly

Exploring the immunology of parasitism--from surface antigens to the hygiene hypothesis [PDF]

open access: yes, 2009
Helminth immunology is a field which has changed beyond recognition in the past 30 years, transformed not only by new technologies from cDNA cloning to flow cytometry, but also conceptually as our definition of host immune pathways has matured.

Characterization of a New Bifunctional and Cold-Adapted Polysaccharide Lyase (PL) Family 7 Alginate Lyase from Flavobacterium sp.

open access: yesMarine Drugs, 2020
Alginate oligosaccharides produced by enzymatic degradation show versatile physiological functions and biological activities. In this study, a new alginate lyase encoding gene alyS02 from Flavobacterium sp. S02 was recombinantly expressed at a high level

Synthetic O‐Polysaccharide Backbone Units for a Single Antigen Vaccine Against Two Major Non‐Typhoidal Salmonella Serovars

open access: yesAngewandte Chemie, EarlyView.
A modular strategy was developed to synthesize tri‐, hexa‐, and nona‐saccharides representing repeating units of the conserved O‐polysaccharide backbone of Salmonella. Conjugates of these glycans to bacteriophage Qβ induced strong IgG responses in mice and rabbits. Antibodies elicited recognized native O‐polysaccharides and conferred protection against

Polysaccharide Recognition by Surfactant Protein D:  Novel Interactions of a C-Type Lectin with Nonterminal Glucosyl Residues [PDF]

open access: yes, 2001
Surfactant protein D (SP-D), a C-type lectin, is an important pulmonary host defense molecule. Carbohydrate binding is critical to its host defense properties, but the precise polysaccharide structures recognized by the protein are unknown.

Gold-catalyzed glycosidation for the synthesis of trisaccharides by applying the armed–disarmed strategy

open access: yesBeilstein Journal of Organic Chemistry, 2013
The synthesis of oligosaccharides is still a challenging task as there is no universal glycosyl donor for the synthesis of all oligosaccharides. The gold catalysis for glycosidation reactions, in which alkynylated glycosides are used, has emerged as one ...

Direct 2,3-O-Isopropylidenation of α-D-Mannopyranosides and the Preparation of 3,6-Branched Mannose Trisaccharides

open access: yesMolecules, 2014
A highly efficient, regioselective method for the direct 2,3-O-isopropylidenation of α-D-mannopyranosides is reported. Treatment of various α-D-mannopyranosides with 0.12 equiv of the TsOH·H2O and 2-methoxypropene at 70 °C gave 2,3-O-isopropylidene-α-D ...
