"X-ray crystal structures of the DUB domains of both AMSH-LP and Sst2 bound to diubiquitin shows Phe403 collapsed onto the Lys63 side chain of the proximal ubiquitin; however, the flap residues appear to retain their mobility even in presence of bound substrate or product (indicated by relatively weak electron density enveloping these residues and higher B-factors than internal residues)."
