After the cleavage, Atg8 exposes a C-terminal glycine residue (Gly 116) to which PE can then be coupled during the following steps. In the first step, the Gly116 residue of Atg8 binds to a cysteine residue of ATG7 via a thioester bond in an ATP-dependent manner. During the second step, Atg8 is transferred … See more Autophagy-related protein 8 (Atg8) is a ubiquitin-like protein required for the formation of autophagosomal membranes.
