UDP- glucose: glycoprotein glucosyltransferase (UGGT) is a protein that operates as the gatekeeper for the endoplasmic reticulum (ER) quality control mechanism of glycoprotein folding. It is known that vertebrates and Caenorhabditis genomes harbor two uggt gene copies that exhibit differences

It is now well known that the addition and trimming of oligosaccharide side chains during post-translational modification play an important role in determining the fate of secretory, membrane, and lysosomal glycoproteins. Recent studies have suggested that trimming of oligosaccharide side
We studied the pharmacokinetics of two synthetic derivatives of 1-deoxynojirimycin in the rat after intravenous administration. The mannosidase IA/B inhibitor 1-deoxymannojirimycin and the glucosidase inhibitor N-methyl-1-deoxynojirimycin exhibited minimal plasma protein binding and showed a rapid biphasic plasma disappearance, with an

A Mucor pusillus mutant defective in asparagine-linked glycosylation was found in our stock cultures. This mutant, designated 1116, secreted aspartic proteinase (MPP) in a less-glycosylated form than that secreted by the wild-type strain. Analysis of enzyme susceptibility, lectin binding, and

Castanospermine, 1-deoxynojirimycin, and N-methyl-1-deoxynojirimycin, three well-characterized inhibitors of the glucosidases involved in the processing of N-linked oligosaccharides, did not affect the biosynthesis or the secretion of exoglucanases (EC 3.2.1.58) from Saccharomyces cerevisiae and Candida albicans but inhibited the activity itself.
