Advanced Science, EarlyView.An artificial bifunctional N‐deacetylase/N‐sulfotransferase was engineered in Escherichia coli by combining screened N‐deacetylases with an NST domain. The integrated engineering strategy improved enzyme performance. The optimized enzyme efficiently converted heparosan into N‐sulfated heparosan, addressing a key bottleneck in microbial heparin ...

Intracellular Delivery of Hydrophilic Glycans Using Superchaotropic Clusters
Angewandte Chemie, EarlyView.Superchaotropic boron clusters are demonstrated to deliver hydrophilic glycans directly into mammalian cells, removing the need for acetylation and cytotoxic solvents such as DMSO. Azido glycans for metabolic oligosaccharide engineering, and trehalose, were delivered and the successful azido‐labelling of glycoproteins, cell surface glycans, and ...

Cap-and-Tag Solid Phase Oligosaccharide Synthesis
, 2016 A new “cap-and-tag” strategy is applied to solid phase oligosaccharide synthesis. Acetyl-capping and fluorous-tagging allowed for the facile separation of the desired F-tagged oligosaccharide from the acetyl-capped deletion sequences using fluorous solid

Advanced Science, EarlyView.Liberation of ferulic acid by gut microbial feruloyl esterase mediates cognitive enhancement of germinated quinoa (GQF) on obese mice. Ferulic acid enriched in GQF is released by gut microbes Roseburia hominis and R. intestinalis and subsequently mediates the neuroprotective effects of GQF on obesity‐induced cognitive decline by activating hippocampal ...
