Protein Disulfide

The product of the EUG1 gene of Saccharomyces cerevisiae is a soluble endoplasmic reticulum protein with homology to both the mammalian protein disulfide isomerase (PDI) and the yeast PDI homolog encoded by the essential PDI1 gene. Deletion or overexpression of EUG1 causes no growth defects under a variety of conditions. EUG1 mRNA and protein levels are dramatically increased in response to the accumulation of native or unglycosylated proteins in the endoplasmic reticulum. Overexpression of the EUG1 gene allows yeast cells to grow in the absence of the PDI1 gene product. Depletion of the PDI1 protein in Saccharomyces cerevisiae causes a soluble vacuolar glycoprotein to accumulate in its endoplasmic reticulum form, and this phenotype is only partially relieved by the overexpression of EUG1. Taken together, our results indicate that PDI1 and EUG1 encode functionally related proteins that are likely to be involved in interacting with nascent polypeptides in the yeast endoplasmic reticulum.

Our understanding of how the endoplasmic reticulum (ER)-associated protein degradation (ERAD) machinery efficiently targets terminally misfolded proteins while avoiding the misidentification of nascent polypeptides and correctly folded proteins is limited. For luminal N-glycoproteins, demannosylation of their N-glycan to expose a terminal α1,6-linked mannose is necessary for their degradation via ERAD, but whether this modification is specific to misfolded proteins is unknown. Here we report that the complex of the mannosidase Htm1p and the protein disulfide isomerase Pdi1p (Htm1p–Pdi1p) acts as a folding-sensitive mannosidase for catalyzing this first committed step in Saccharomyces cerevisiae. We reconstitute this step in vitro with Htm1p–Pdi1p and model glycoprotein substrates whose structural states we can manipulate. We find that Htm1p–Pdi1p is a glycoprotein-specific mannosidase that preferentially targets nonnative glycoproteins trapped in partially structured states. As such, Htm1p–Pdi1p is suited to act as a licensing factor that monitors folding in the ER lumen and preferentially commits glycoproteins trapped in partially structured states for degradation.
