Shown in the top row are three types of ubiquitin-protein ligases that regulate eukaryotic cell cycle by proteasome-mediated proteolysis. Compare them in the table. SCF APC/CCdc20 APC/CCdh1 From late anaphase throughout G (in addition to mitotic cyclin) At which phase/stage of the cell cycle does each of these ubiquitin- protein ligases function? What protein is targeted to proteolysis by each of these ubiquitin-protein ligases? Which of these ubiquitin-protein ligases facilitates separation of sister chromatids?
