The anaphase-promoting complex/cyclosome (APC/C) is an E3 ubiquitin ligase composed of approximately 13 distinct subunits required for progression through meiosis, mitosis, and the G1 phase of the cell cycle. Despite its central role in these processes, information concerning its composition and structure is limited. Here, we determined the structure of yeast APC/C by cryo-electron microscopy (cryo-EM). Docking of tetratricopeptide repeat (TPR)-containing subunits indicates that they likely f...Expand abstract
