Autophagy is a dynamic membrane phenomenon for bulk protein degradation in the lysosome/vacuole. Apg8/Aut7 is an essential factor for autophagy in yeast. We previously found that the carboxy-terminal arginine of nascent Apg8 is removed by Apg4/Aut2 protease, leaving a glycine residue at the C terminus. Apg8 is then converted to a form (Apg8-X) that is(More)
Autophagy involves de novo formation of double membrane-bound structures called autophagosomes, which engulf material to be degraded in lytic compartments. Atg8 is a ubiquitin-like protein required for this process in Saccharomyces cerevisiae that can be conjugated to the lipid phosphatidylethanolamine by a ubiquitin-like system. Here, we show using an in(More)
Autophagy and the Cvt pathway are examples of nonclassical vesicular transport from the cytoplasm to the vacuole via double-membrane vesicles. Apg8/Aut7, which plays an important role in the formation of such vesicles, tends to bind to membranes in spite of its hydrophilic nature. We show here that the nature of the association of Apg8 with membranes(More)
