With ATG4, may mediate the delivery of the vesicles and autophagosomes to the vacuole via the microtubule cytoskeleton. Participates also in membrane fusion events that take place in the early secretory pathway.<ref>PMID:8224160</ref> <ref>PMID:7593182</ref> <ref>PMID:9649430</ref> <ref>PMID:10525546</ref> <ref>PMID:10681575</ref> <ref>PMID:10837468</ref> <ref>PMID:11038174</ref> <ref>PMID:11100732</ref> <ref>PMID:11149920</ref> | ||

| + | E1 enzymes activate ubiquitin-like proteins and transfer them to cognate E2 enzymes. Atg7, a noncanonical E1, activates two ubiquitin-like proteins, Atg8 and Atg12, and plays a crucial role in autophagy. Here, we report crystal structures of full-length Atg7 and its C-terminal domain bound to Atg8 and MgATP, as well as a solution structure of Atg8 bound to the extreme C-terminal domain (ECTD) of Atg7. The unique N-terminal domain (NTD) of Atg7 is responsible for Atg3 (E2) binding, whereas its C-terminal domain is comprised of a homodimeric adenylation domain (AD) and ECTD. The structural and biochemical data demonstrate that Atg8 is initially recognized by the C-terminal tail of ECTD and is then transferred to an AD, where the Atg8 C terminus is attacked by the catalytic cysteine to form a thioester bond. Atg8 is then transferred via a trans mechanism to the Atg3 bound to the NTD of the opposite protomer within a dimer. | ||
