<ref>The 9-model [[Morphs|morph]] file can be downloaded from [[Image:3dpl_3dqv_acr_morph.pdb]]. The morph represents the change from [[3dpl]] to [[3dqv]], and only chains C and R which are common to these two models. Only one trimer was used from 3dqv (which contains 2 trimers in the asymmetric unit), namely, the one with chains named A, C, and R. This trimer was obtained from [http://www.ebi.ac.uk/msd-srv/pqs/pqs-bin/macmol.pl?filename=3DQV PQS] as 3dqv_1.mmol. The morph was performed by the Yale Morph Server (beta server), ID b899128-21508. This produced 8 models numbered 0-7. In the product morph, the orientation of the final chains was not changed.

In the product morph, the orientation of the final chains was not changed. Hence, chain A (NEDD8) from 3dqv.pdb was added as model number 8 (9th model) without the need for special alignment.

from a Cullin-RING ligase complex ([[3dpl]]) to the same complex after NEDD8ylation (covalent addition of the NEDD8 ubiquitin-like chain to LysXXX of Cullin; [[3dqv]]). NEDD8 binds and rotates the C-terminal domain of Cullin, releasing the folded RING domain from its Cullin-binding site. RING remains attached to Cullin by the RING N-terminus which remains embedded in Cullin. | from a Cullin-RING ligase complex ([[3dpl]]) to the same complex after NEDD8ylation (covalent addition of the NEDD8 ubiquitin-like chain to LysXXX of Cullin; [[3dqv]]).
