Abstract:
... Protein glycosylation is one of the most common post-translational modifications present in the eukaryotic cell. The N-linked glycosylation is a biosynthetic pathway where an oligosaccharide is added to asparagine residues within the endoplasmic reticulum. Upon addition of the N-linked glycan to nascent proteins, α-glucosidase I removes the outermost α1,2-glucose unit from the N-linked core Glc₃Ma ...

Abstract:
... Yeasts are common inhabitants of different types of aquatic habitats, including marine and estuarine waters and rivers. Although numerous studies have surveyed yeast occurrence in these habitats, the identification of autochthonous populations has been problematic because several yeast species seem to be very versatile and therefore mere presence is not sufficient to establish an ecological associ ...

Abstract:
... Ralstonia solanacearum biovar 2, a key bacterial pathogen of potato, has recently established in temperate climate waters. On the basis of isolates obtained from diseased (potato) plants, its genome has been assumed to be virtually clonal, but information on environmental isolates has been lacking. Based on differences in pulsed-field gel electrophoresis patterns, we compared the genomes of two bi ...
