Proposed article title: Release of RING from Cullin by NEDD8ylation

At right is a morph [1] 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.
Notes and ReferencesNotes and References
- ↑ The 9-model morph file can be downloaded from File: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 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. Hence, chain A (NEDD8) from 3dqv.pdb was added as model number 8 (9th model) without the need for special alignment. Morph done by Eric Martz at the request of Raymond J. Deshaies of CalTech.
