Biosynthesis of glycosylated 5-hydroxycytosine in the DNA of diverse viruses

The paper identifies 5-hydroxycytosine (5hoC) as a precursor for glycosylated cytosine derivatives in viral DNA, revealing a novel mechanism for evading host defenses.

Elevated colonic microbiota-associated paucimannosidic and truncated N-glycans in pediatric ulcerative colitis

This study identifies elevated paucimannosidic and truncated N-glycans in the microbiota of pediatric ulcerative colitis patients compared to controls, suggesting a potential role for glycan metabolism in disease pathogenesis.

A Chemoenzymatic Method for Glycoproteomic N-glycan Type Quantitation

The paper introduces a chemoenzymatic method to quantitatively analyze N-glycan types on glycoproteins, demonstrating its application in characterizing glycan heterogeneity in IgG1 and MCF7 cells.

Genetic and chemical differentiation of Campylobacter coli and Campylobacter jejuni lipooligosaccharide pathways

The paper investigates genetic and chemical diversity of lipooligosaccharides (LOS) in C. coli, identifying species-specific features distinguishing it from C. jejuni.
