Copper is an essential co-factor for all organisms, and yet it becomes toxic if concentrations exceed a threshold maintained by evolutionarily conserved homeostatic mechanisms. How excess copper induces cell death, however, is unknown. Here, we show in human cells that copper-dependent, regulated cell death is distinct from known death mechanisms, and is dependent on mitochondrial respiration. We show that copper-dependent death occurs via direct binding of copper to lipoylated components of the tricarboxylic acid (TCA) cycle. This results in lipoylated protein aggregation and subsequent iron-sulfur cluster protein loss leading to proteotoxic stress and ultimately cell death. These findings may explain the need for ancient copper homeostatic mechanisms. Copper-induced cell death is regulated by mitochondrial ferredoxin 1-mediated protein lipoylation.
