NMR Refinement
Method	Details	Software
simulated annealing	Docking was carried out between the two proteins using rigid body simulated annealing with a flexible linker between diubiquitin domains. Initial structures were 3H7P and 2MJB for ubiquitin, and 1S1Q for Tsg101 UEV. Distal domain and Tsg101 backbone were fixed to 1S1Q position. Following initial docking, the lowest energy structure in each of the two clusters was used as input for refinement, with an ensemble number of 2.	X-PLOR NIH
