Biosynthesis of O-N-acetylgalactosamine glycans in the human cell nucleus [PDF]

Journal of Biological Chemistry, 2019
يتم تنظيم الوظائف البيولوجية للبروتينات النووية من خلال تعديلات ما بعد الترجمة (PTMs) التي تعدل التعبير الجيني والفيزيولوجيا الخلوية. ومع ذلك، لم يتم الإبلاغ سابقًا عن دور الجليكوزيل المرتبط بـ O (O - GalNAc) باعتباره PTM للبروتينات النووية في الخلية البشرية. هنا، درسنا بالتفصيل بدء التخليق الحيوي O -GalNAc glycan، الذي يمثل PTM جديد للبروتينات النووية

Development of a fluorometric microtiter plate based enzyme assay for MPS IVA (Morquio type A) using dried blood spots

Molecular Genetics and Metabolism Reports, 2014
Mucopolysaccharidosis type IVA or Morquio type-A disease is a hereditary lysosomal storage disorder caused by deficient activity of the lysosomal enzyme N-acetylgalactosamine-6-sulfate sulfatase (GALNS). The disease is caused by lysosomal accumulation of

Characterization of Lysosomal Hydrolases and Transporters and Their Age‐Dependent Variability: Relevance to Drug Metabolism and Transport of Small Molecule and Biologic Drugs

Clinical Pharmacology &Therapeutics, EarlyView.
Lysosomes play a key role in the accumulation, catabolism, and transport of endogenous and exogenous metabolites and proteins and are involved in drug metabolism and prodrug activation. However, the protein abundance and interindividual variability of lysosomal drug‐metabolizing enzymes and transporters (DMETs) remain underexplored.

Low Levels of Natural Anti-α-N-Acetylgalactosamine (Tn) Antibodies Are Associated With COVID-19

Frontiers in Microbiology, 2021
Human serum contains large amounts of anti-carbohydrate antibodies, some of which may recognize epitopes on viral glycans. Here, we tested the hypothesis that such antibodies may confer protection against COVID-19 so that patients would be preferentially

Effects of high‐moisture extrusion processing on reducing anti‐nutritional factors and allergenicity in plant‐based materials—A mini review

Food Biomacromolecules, EarlyView.
Abstract The rising demand for plant‐based meat alternatives has had advancements in processing technologies such as extrusion to meet consumer preferences for enhanced sensory qualities and nutritional benefits. High moisture extrusion (HME), a thermo‐mechanical process employing elevated moisture levels (40%–70%), has emerged as a promising method ...

N-acetylgalatosamine-mediated regulation of the aga operon by AgaR in Streptococcus pneumoniae

Frontiers in Cellular and Infection Microbiology, 2016
Here, we analyze the transcriptomic response of Streptococcus pneumoniae D39 to N-acetylgalactosamine (NAGa). Transcriptome comparison of S. pneumoniae D39 grown NAGaM17 (0.5% NAGa + M17) to that grown in GM17 (0.5% Glucose + M17) revealed the elevated ...

Mass Spectrometry Insights Into Post‐Translational Modifications in Extracellular Vesicles

Mass Spectrometry Reviews, EarlyView.
ABSTRACT Extracellular vesicles (EVs) are membrane‐enclosed structures secreted by virtually all living cells, serving as essential mediators of intercellular communication in both physiological and pathological processes. There is growing interest in their potential applications as biomarkers, therapeutic targets, and drug delivery systems, which ...

Chondroitin sulfate disaccharide is a specific and sensitive biomarker for mucopolysaccharidosis type IVA

JIMD Reports, 2020
Mucopolysaccharidosis type IVA (MPS IVA) is an inborn error of glycosaminoglycan (GAG) catabolism characterized by a deficiency of the lysosomal enzyme, N‐acetylgalactosamine 6‐sulphatase (GALNS).
