The crystal structure of Saccharomyces cerevisiae Atg3The crystal structure of Saccharomyces cerevisiae Atg3
Structural highlights
2dyt is a 1 chain structure with sequence from Saccharomyces cerevisiae. Full crystallographic information is available from OCA. For a guided tour on the structure components use FirstGlance.
ATG3_YEAST E2 conjugating enzyme responsible for the E2-like covalent binding of phosphatidylethanolamine to the C-terminal Gly of ATG8. This step is required for the membrane association of ATG8. The formation of the ATG8-phosphatidylethanolamine conjugate is essential for autophagy and for the cytoplasm to vacuole transport (Cvt).[1][2][3][4][5][6]
