A UbcH5/Ubiquitin Noncovalent Complex Is Required for Processive BRCA1-Directed Ubiquitination.
P.S.Brzovic, A.Lissounov, D.E.Christensen, D.W.Hoyt, R.E.Klevit.
Protein ubiquitination is a powerful regulatory modification that influences nearly every aspect of eukaryotic cell biology. The general pathway for ubiquitin (Ub) modification requires the sequential activities of a Ub-activating enzyme (E1), a Ub transfer enzyme (E2), and a Ub ligase (E3). The E2 must recognize both the E1 and a cognate E3 in addition to carrying activated Ub. These central functions are performed by a topologically conserved alpha/beta-fold core domain of approximately 150 residues shared by all E2s. However, as presented herein, the UbcH5 family of E2s can also bind Ub noncovalently on a surface well removed from the E2 active site. We present the solution structure of the UbcH5c/Ub noncovalent complex and demonstrate that this noncovalent interaction permits self-assembly of activated UbcH5c approximately Ub molecules. Self-assembly has profound consequences for the processive formation of polyubiquitin (poly-Ub) chains in ubiquitination reactions directed by the breast and ovarian cancer tumor susceptibility protein BRCA1.

The most recent references are shown first. Citation data come partly from CiteXplore and partly from an automated harvesting procedure. Note that this is likely to be only a partial list as not all journals are covered by either method. However, we are continually building up the citation data so more and more references will be included with time. Where a reference describes a PDB structure, the PDB code is shown on the right.
