Figure 1. Models of yeast Atg3. (A) The crystal structure of Atg3 in solution (PDB ID: 2DYT³⁰). The missing protein regions are listed on the right side of the panel, and the amino acid residues at the border with the missing regions are denoted directly in the ribbon model. (B) The crystal structure of Atg3 in a complex with Atg7 (Atg7 not shown) (PDP ID: 4GSL²⁸). The missing regions and border residues are shown as in (A). (C) Hypothetical structural model of Atg3 in solution. The extended disordered conformation of Atg3 is depicted schematically, and includes disordered domains that are not visible in the published crystal structure.³⁰ Structural models were created using DeepView/Swiss-PDBViewer v.4.0.4 available at http://spdbv.vital-it.ch/.
