(A) Superposition of one Ubp8 monomer in the domain-swapped DUBm complex lacking the Sgf11-ZnF (green) with Ubp8 in intact DUBm complex (gray) showing altered position of N141.
(B) Superposition as in (A) showing the second Ubp8 monomer (purple) in the domain-swapped complex in which N141 disordered.
(C, D) Superpositions as in (A) showing Ubp8 in the domain-swapped DUBm-ΔSgf11-ZnF complex containing Ubp8S144N. Coloring as in (A)
