Cullin-RING-type E3 NEDD8 transferase.
based on mapping to UniProt Q969M7
S-[NEDD8-protein]-yl-[E2 NEDD8-conjugating enzyme]-L-cysteine + [cullin]- L-lysine = [E2 NEDD8-conjugating enzyme]-L-cysteine + N(6)-[NEDD8- protein]-yl-[cullin]-L-lysine.
-!- Some RING-type E3 ubiquitin transferase (EC 2.3.2.27) are not able to bind a substrate protein directly. -!- Instead, they form a complex with a cullin scaffold protein and a substrate recognition module, which is named CRL for Cullin-RING- Ligase. -!- The cullin protein needs to be activated by the ubiquitin-like protein NEDD8 in a process known as neddylation. -!- The transfer of NEDD8 from a NEDD8-specific E2 enzyme onto the cullin protein is a secondary function of the RING-type E3 ubiquitin transferase in the CRL complex. -!- The process requires auxiliary factors that belong to the DCN1 (defective in cullin neddylation 1) family.
