Structural analysis of recombinant human ubiquitin-conjugating enzyme UbcH5c
UbcH5c belongs to the ubiquitin-conjugating enzyme family and plays an important role in catalyzing ubiquitination during TNF-α--triggered NF-κB activation. Therefore, UbcH5c is a potent therapeutic target for the treatment of inflammatory and autoimmune diseases induced by aberrant activation of NF-κB. In this study, we established a stable expression system for recombinant UbcH5c and solved t...
متن کاملCyclization of polyubiquitin by the E2-25K ubiquitin conjugating enzyme.
For most substrates of ubiquitin (Ub)-dependent degradation, recognition by the proteasome is mediated by a covalently attached signal assembled from multiple ubiquitins linked to each other via the C terminus of one Ub and the epsilon-amine of Lys(48) of another Ub. Among Ub-conjugating enzymes, E2-25K is unique in its ability to synthesize in vitro unanchored Lys(48)-linked poly-Ub chains fro...
متن کاملA Giant Ubiquitin-conjugating Enzyme Related to IAP Apoptosis Inhibitors
Ubiquitin-conjugating enzymes (UBC) catalyze the covalent attachment of ubiquitin to target proteins and are distinguished by the presence of a UBC domain required for catalysis. Previously identified members of this enzyme family are small proteins and function primarily in selective proteolysis pathways. Here we describe BRUCE (BIR repeat containing ubiquitin-conjugating enzyme), a giant (528...
متن کاملAn Allosteric Inhibitor of the Human Cdc34 Ubiquitin-Conjugating Enzyme
In the ubiquitin-proteasome system (UPS), E2 enzymes mediate the conjugation of ubiquitin to substrates and thereby control protein stability and interactions. The E2 enzyme hCdc34 catalyzes the ubiquitination of hundreds of proteins in conjunction with the cullin-RING (CRL) superfamily of E3 enzymes. We identified a small molecule termed CC0651 that selectively inhibits hCdc34. Structure deter...
متن کاملSequence of a cloned tomato ubiquitin conjugating enzyme.
Ubiquitin is a small, abundant protein that is seemingly present in a11 eukaryotic cells and that is covalently ligated to specific protein substrates via an ATP-dependent reaction. This ubiquitinous has been demonstrated to target proteins for subsequent cellular degradation. Briefly, the process involves activation of ubiquitin, catalyzed by ubiquitin-activating enzymes, transfer to a family ...
