Structural analysis sheds light on APC/C-mediated ubiquitylation.
In the December 22nd issue of Molecular Cell, two groups report refined cryo-electron microscopic structures of the APC/C at approximately 20 A resolution. They also reveal important new features including multiple copies of subunits, dimerization and structural flexibility of the APC/C, which give a hint to solve the mechanisms of the APC/C-dependent ubiquitylation.
