Membrane transforming (IMAGE) Japan Science and Technology Agency Caption Figure 1. Membrane transforming activity of lipidated Atg8?(a) Upon lipidation, prolate membranes are constricted at the hollow region and transformed into a pear-like shape. DIC, differential interference contrast. Scale bars, 10 μm. (b) The area difference between the outer and inner layers of the membrane, &Delta;a, is increased due to the interaction of the aromatic amino acids in lipidated Atg8 with the outer layer, leading to membrane deformation. PC, phosphatidylcholine. PE, phosphatidylethanolamine. Credit © Nobuo N.
