A Ca2+-induced mitochondrial permeability transition causes complete release of rat liver endonuclease G activity from its exclusive location within the mitochondrial intermembrane space. Identification of a novel endo-exonuclease activity residing within the mitochondrial matrix. Davies A.M., Hershman S., Stabley G.J., Hoek J.B., Peterson J., Cahill A.

The authors would like to apologise for indicating that the amount of calcium used to induce a mitochondrial permeability transition was 1 µM, when the correct amount was 1 mM. Please refer to the first sentence under the heading ‘Induction of the mitochondrial permeability transition’ in the Materials and Methods, and also to Figure 5A and its accompanying legend.
