Production of Glycopeptide Derivatives for Exploring Substrate Specificity of Human OGA Toward Sugar Moiety. [PDF]

open access: yes, 2018
O-GlcNAcase (OGA) is the only enzyme responsible for removing N-acetyl glucosamine (GlcNAc) attached to serine and threonine residues on proteins. This enzyme plays a key role in O-GlcNAc metabolism.

Structure analysis of biologically important prokaryotic glycopolymers [PDF]

open access: yes, 2013
Of the many post-translational modifications organisms can undertake, glycosylation is the most prevalent and the most diverse. The research in this thesis focuses on the structural characterisation of glycosylation in two classes of glycopolymer (

Coacervate‐Mediated Lysosome‐Targeting Antibody Delivery for Protein Degradation

open access: yesAdvanced Science, EarlyView.
Targeting coacervates to the lysosome in the cytoplasm is a challenge. Here, we convert a tetrapeptide into lysosome‐targeting, membrane‐translocating coacervates. The lysosome‐sorting peptide coacervates facilitate coacervate‐mediated delivery of antibody antigen complexes and a PROTAC compound to the lysosome for the targeted degradation of cancer ...

Hierarchical Channeled Graphitized Nanoarchitecture as a Diagnostic Platform for Maternal Fever Warning

open access: yesAdvanced Science, EarlyView.
This study presents a hierarchically channeled graphitized nanoarchitecture (HPGC‐Z67) as a novel nano‐diagnostic platform. It enables sensitive and efficient N‐glycan extraction from plasma, significantly reducing processing time and cost. The platform identifies pivotal N‐glycans to accurately differentiate between infectious and non‐infectious ...

Theonellamides J and K and 5-cis-Apoa-theopalauamide, Bicyclic Glycopeptides of the Red Sea Sponge Theonella swinhoei

open access: yesMarine Drugs, 2021
Theonella swinhoei is a fairly common inhabitant of reefs throughout the Indian and Pacific Oceans. Metabolomic analyses of samples of T. swinhoei collected in different depths in the Gulf of Aqaba revealed two chemotypes differing in the profiles of the

Glycopeptide antibiotic biosynthesis [PDF]

open access: yesThe Journal of Antibiotics, 2013
Glycopeptides such as vancomycin, teicoplanin and telavancin are essential for treating infections caused by Gram-positive bacteria. Unfortunately, the dwindled pipeline of new antibiotics into the market and the emergence of glycopeptide-resistant enterococci and other resistant bacteria are increasingly making effective antibiotic treatment difficult.

Sustainable Phosphorylated Cellulose Nanocrystals: A Dual‐Affinity Platform for High‐Efficiency Enrichment of Intact Glycopeptides and Phosphopeptides

open access: yesAdvanced Science, EarlyView.
AAA ABSTRACT Protein glycosylation and phosphorylation are critical post‐translational modifications (PTMs) governing nearly all cellular functions, yet their analysis remains challenging due to reliance on costly and unsustainable enrichment materials.

Glyco-signatures in patients with advanced lung cancer during anti-PD-1/PD-L1 immunotherapy

open access: yesActa Biochimica et Biophysica Sinica
Immune checkpoint inhibitors (ICIs) targeting programmed cell death 1/programmed cell death ligand-1 (PD-1/PD-L1) have significantly prolonged the survival of advanced/metastatic patients with lung cancer. However, only a small proportion of patients can

Structural Insights From HIV-Antibody Co-Evolution And Related Immunization Studies [PDF]

open access: yes, 2018
Human immunodeficiency virus type 1 (HIV-1) is a rapidly evolving pathogen and causes the acquired immunodeficiency syndrome (AIDS) in humans. There are ~30-35 million people infected with HIV around the world, and ~25 million have died since the first ...
