DGSA-distance geometry simulated annealing	In this work, the dimer structure of p62 PB1 was determined by using a rigid-body docking calculation based on the pseudo-contact shift. In the docking calculation, the coordinates of chain A were held fixed, whereas the coordinates of chain B were treated as a rigid body and set free to rotate and translate. The differences among the models are relative orientations between chain A and chain B, not each coordinates. In the calculation, monomer structures of DR and KE were docked each other based on the inter-subunit restraints from pseudo-contact shifts. The coordinates of DR and KE were generated from the monomer structure of DR (2kkc), using PyMOL software. For pseudo-contact shift restraints, we need a paramagnetic lanthanide ion fixed in the target protein. To fix a lanthanide ions to DR, we utilized the lanthanide binding peptide tag (LBT).The chain A represents LBT-DR, and chain B does KE. We collected the pseudo-contact shift restrains using LBT-DR/KE complex, while the docking calculations were performed using the coordinates without LBT.	Olivia
