It has been proposed that in rat and murine tissues glucosidase II (GII) is formed by two subunits, GIIalpha and GIIbeta, respectively, responsible for the catalytic activity and the retention of the enzyme in the endoplasmic reticulum (ER). To test this proposal we disrupted genes (gls2alpha(+) and gls2beta(+)) encoding GIIalpha and GIIbeta homologs in(More)
The UDP-Glc:glycoprotein glucosyltransferase was purified to homogeneity from the fission yeast Schizosaccharomyces pombe. The enzyme has been recently suggested to be involved in the mechanism by which unfolded, partially folded, or misfolded glycoproteins are retained in the endoplasmic reticulum. The pure yeast glucosyltransferase formed protein-linked(More)
We have identified and begun the characterization of the gene encoding UDP-Glc:glycoprotein glucosyltransferase in Schizosaccharomyces pombe. This gene, here designated gpt1, codes for a polypeptide having a signal peptide of 18 amino acids followed by 1429 amino acids with no transmembrane domain, as expected for a soluble protein of the endoplasmic(More)
A key element in the quality control of glycoprotein folding is the UDP-Glc:glycoprotein glucosyltransferase (GT), which in cell-free assays exclusively glucosylates misfolded glycoproteins. In order to test if such a protein conformation is a sufficient condition for in vivo glucosylation of all N-linked oligosaccharides by GT, a Schizosaccharomyces pombe(More)
