Researchers have been able to view in detail, and for the first time, the previously mysterious process by which long chains of a protein called ubiquitin are added by enzymes called ubiquitin ligases to proteins that control the cell cycle. Ubiquitin chains tag target proteins for destruction by protein-degrading complexes in the cell.
