Chemoenzymatic synthesis and structural characterization of 2-O-sulfated glucuronic acid-containing heparan sulfate hexasaccharides.

Glycobiology, 2014
Heparan sulfate and heparin are highly sulfated polysaccharides that consist of a repeating disaccharide unit of glucosamine and glucuronic or iduronic acid. The 2-O-sulfated iduronic acid (IdoA2S) residue is commonly found in heparan sulfate and heparin;

Glucuronoyl Esterase Screening and Characterization Assays Utilizing Commercially Available Benzyl Glucuronic Acid Ester

Molecules, 2015
Research on glucuronoyl esterases (GEs) has been hampered by the lack of enzyme assays based on easily obtainable substrates. While benzyl d-glucuronic acid ester (BnGlcA) is a commercially available substrate that can be used for GE assays, several ...

Misincorporation of Galactose by Chondroitin Synthase of Escherichia coli K4: From Traces to Synthesis of Chondbiuronan, a Novel Chondroitin-Like Polysaccharide

Biomolecules, 2020
Chondroitin synthase KfoC is a bifunctional enzyme which polymerizes the capsular chondroitin backbone of Escherichia coli K4, composed of repeated β3N-acetylgalactosamine (GalNAc)-β4-glucuronic acid (GlcA) units. Sugar donors UDP-GalNAc and UDP-GlcA are

Photo‐triggered Hyaluronic Acid Hydrogel for 3D Culture and Cell Recovery

ChemBioChem, Accepted Article.
Properties of semi‐synthetic hydrogels can be fine‐tuned making these attractive for various applications in regenerative medicine. Here, we describe a hydrogel platform based on hyaluronic acid (HA) modified by (1R,8S,9S)‐bicycle[6.1.0]non‐4‐yn‐9‐ylmethanol (BCN) and a cross‐linker composed of light sensitive o‐nitrobenzyl and polyethylene glycol (PEG)

Electrocatalytic Glucose Upgrading by Sulfonated Carbon for Sustainable Manufacturing

ChemCatChem, EarlyView.
We are one step closer to sustainable manufacturing after successfully converting glucose into various raw materials (oxalic acid, gluconic acid, tartaric acid, maleic acid, glycolic acid, arabinose, formic acid, acetic acid, and 5‐hydroxymethylfurfural) by electrocatalytic oxidation with a sulfonated carbon catalyst. Abstract In a sustainable economy,
