    Abstract : UDP-sugar metabolizing pyrophosphorylases provide the primary mechanism for de novo synthesis of UDP-sugars, which can then be used for myriads of glycosyltranferase reactions, producing cell wall carbohydrates, sucrose, glycoproteins and glycolipids, as well as many other glycosylated compounds. The pyrophosphorylases can be divided into three families: UDP-Glc pyrophosphorylase (UGPase), UDP-sugar pyrophosphorylase (USPase) and UDP-N-acety lglucosamine pyrophosphorylase (UAGPase), which can be discriminated both by differences in accepted substrate range and amino acid sequences.

  2. 2. Bacterial modulation of host glycosylation - in infection, biotechnology, and therapy

    Author : Jonathan Sjögren; Infektionsmedicin; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; IgG; endoglycosidase; Streptococcus pyogenes; glycosylation; EndoS;

    Abstract : A majority of the proteins of the immune system are glycosylated and the glycans of IgG are essential for its functionality. Bacteria display enzymes that modulate the glycans of the immune system to weaken the host defense and favor bacterial survival. READ MORE

  3. 3. Development and application of alternative methods for profiling proteins N-glycosylation

    Author : Alessandro Quaranta; Leopold Ilag; Niclas Karlsson; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; N-glycosylation; Glycomics; Glycosylation Biomarkers; Intact Glycoproteins; Glycoform Quantification; Mass Spectrometry; Ion Mobility Spectrometry; MALDI-MS; Paper Spray Ionization; Microfluidics; Magnetic Beads; Immunoaffinity Purification; Nanobodies; Analytical Chemistry; analytisk kemi;

    Abstract : Glycosylation is a post-translational modification (PTM) that exerts profound structural and functional effects on the modified protein. Glycan synthesis and conjugation to proteins are regulated by a myriad of factors, both genetic and environmental, and are also influenced by external stressors. READ MORE

  4. 4. Ligation-mediated Molecular Analysis of Influenza Subtypes, Splicing and Protein Glycosylation

    Author : Tim Conze; Ulf Landegren; Mats Nilsson; Ola Söderberg; Jörn Glökler; Uppsala universitet; []

    Abstract : Binder-based assays are employed throughout the life sciences. Powerful signal amplification techniques have enabled detection of very rare molecule species diluted in simple buffers. Unspecific binding of primary binders leads to increased background in more complex samples. READ MORE

  5. 5. Development of mathematical modelling for the glycosylation of IgG in CHO cell cultures

    Author : Liang Zhang; Véronique Chotteau; Michael J. Betenbaugh; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chinese hamster ovary cells; glycosylation; IgG; mathematical modelling; experimental design; perfusion; carbon sources; GReBA; Bayesian network; probabilistic graphic model; Biotechnology; Bioteknologi;

    Abstract : Chinese hamster ovary (CHO) cells are the most popular expression system for the production of biopharmaceuticals. More than 80% of the approved monoclonal antibodies (mAbs) or immunoglobulin G (IgG) are produced with these cells. Glycosylation is a usual post- translational modification important for therapeutic mAbs. READ MORE
