Abstract:
Abstract Glycans, as a part of glycoproteins, glycolipids and other glycoconjugates, are involved in many vital intra- and inter-cellular tasks, such as protein folding and sorting, protein quality control, vesicular trafficking, cell signalling, immunological defence, cell motility and adhesion. Therefore, their correct construction is crucial for the normal functioning of eukaryotic cells and organisms they form. Most cellular glycans are constructed in the Golgi, and abnormalities in their structure may derive, for instance, from alkalinization of the Golgi lumen. In this work we show th

IgA nephropathy (IgAN) is a common glomerulonephritis characterised by deposition of IgA1 in the glomerular mesangium The underlying abnormality lies within the IgA system rather than the kidney, and modest irregularities of IgA biology have been described, but the mechanisms involved in IgA1 deposition and glomerular injury remain elusive. A few reports have suggested an abnormality of the carbohydrate component of IgA1 in IgAN.

Bacteria in this genus are prolific producers of antibiotics and are often phenotypically resistant to multiple antibiotics.

Asymmetric control of glycosylation was achieved through this adapted catalytic system. Both enantiomers of the catalyst ((R) and (S)
