Discovery and Biosynthesis of the Novel Glycotetrapeptide Antibiotic Biffamycin A

open access: yesAngewandte Chemie, EarlyView.
Genetic de‐regulation of a silent biosynthetic pathway allowed isolation and characterisation of a novel glycopeptide antibiotic named biffamycin A, which harbours unprecedented 5‐chloro‐4‐methoxy tryptophan and 3R‐hydroxy(α‐D‐mannoysl)‐D‐lysine moieties and is bioactive against MRSA and VRSA.

Comparison of Different HILIC Stationary Phases in the Separation of Hemopexin and Immunoglobulin G Glycopeptides and Their Isomers

open access: yesMolecules, 2020
Protein glycosylation analysis is challenging due to the structural variety of complex conjugates. However, chromatographically separating glycans attached to tryptic peptides enables their site-specific characterization.

Total Chemical Synthesis of Interleukin‐15 and Interleukin‐2: Taming Protein Hydrophobicity and Aggregation by a Versatile Solubilizing Strategy

open access: yesAngewandte Chemie, EarlyView.
A reducible solubilizing tag strategy (RST‐2.0) enables the synthesis, purification and ligation of difficult peptides while being readily removable just during folding, which overcomes the common challenges from protein hydrophobicity and aggregation. With this method, we achieved the first total synthesis of native and N‐glycosylated IL‐15 as well as

Precursor ion scanning for detection and structural characterization of heterogeneous glycopeptide mixtures

open access: yes, 2002
The structure of N-linked glycans is determined by a complex, anabolic, intracellular pathway but the exact role of individual glycans is not always clear.

Retention mechanism and enrichment of glycopeptides on titanium dioxide

open access: yes, 2013
A uniform method for the facile and selective enrichment of glycopeptides with titanium dioxide (TiO2) is presented. Retention mechanisms between glycopeptides and TiO2 were explored by checking the influence of acetonitrile content, NH3 center dot H2O ...

Characterization of the Streptomyces coelicolor Glycoproteome Reveals Glycoproteins Important for Cell Wall Biogenesis

open access: yesmBio, 2019
The physiological role of protein O-glycosylation in prokaryotes is poorly understood due to our limited knowledge of the extent of their glycoproteomes.

Efficient enrichment of glycopeptides using phenylboronic acid polymer brush modified silica microspheres

open access: yes, 2014
For the development of rapid glycopeptide enrichment materials, conventional monolayer phenylboronic acid (PBA) based materials inevitably encounter many problems, such as low loading efficiency, long incubation time, and unsatisfactory selectivity ...
