Cell surfaces are endowed with biological functionality designed to mediate extracellular communication. The cell-surface repertoire can be expanded to include abiotic functionality through the biosynthetic introduction of unnatural sugars into cellular glycans, a process termed metabolic oligosaccharide engineering. This technique has been exploited in fundamental studies of glycan-dependent cell–cell and virus–cell interactions and also provides an avenue for the chemical remodelling of…

Remodeling of Cellular Surfaces via Fast Disulfide-Thiol Exchange to Regulate Cell Behaviors.

TLDR
A sequential layer by layer assembly process was developed to grow albumin pro-tein shells on cellular surfaces fixed by disulfide-linked network, in a cytocompatible manner, and was well validated on tumor cell, immune cell, and neutrophils showing its potential universality for most of the cells that are rich in thiols.

A chemical approach for identifying O-GlcNAc-modified proteins in cells

TLDR
A chemical strategy directed toward identifying O-GlcNAc-modified proteins from living cells or proteins modified in vitro is described, in vitro, that each enzyme in the hexosamine salvage pathway, and the enzymes that affect this dynamic modification, tolerate analogues of their natural substrates in which the N-acyl side chain has been modified to bear a bio-orthogonal azide moiety.

TLDR
N-butanoylmannosamine blocked polysialylation of NCAM and significantly reduced neurite outgrowth comparable with enzymatic removal of PSA by endoneuraminidases, and subtle structural differences in PSA resulting from the incorporation of SiaProp residues do not alter the antiadhesive properties of polysIALylated NCAM.
