The generation of free N-glycans, or unconjugated oligosaccharides derived from N-linked glycoproteins, is well understood, but whether a similar fate awaits O-linked glycoprotein carbohydrates was unknown. Hirayama et al. now reveal, by using only mannose as an energy source, the generation of free O-glycans in Saccharomyces cerevisiae, in the lumen of a secretory compartment, possibly the vacuole. These findings uncover the presence of a possible regulated degradation pathway for O-mannosylated glycoproteins.
