The authors of “Precursor Oxidation by Mia40 and Erv1 Promotes Vectorial Transport of Proteins into the Mitochondrial Intermembrane Space” (Mol. Biol. Cell [2008] 19, 226–236; originally published in MBoC In Press as 10.1091/mbc.E07-08-0814) wish to make a correction to Figures 5B (bottom panel) and 6D. They erroneously used incorrect panels for these figures. The corrected Figures 5B and 6D appear below. There is no change to the conclusions of the paper.
