Fig. 2. Erv1p function is not required for normal activity of mitochondrial Fe/S proteins. Mitochondria were isolated from wild-type (WT) and Erv1^ts cells that were grown for 5 h in lactate media containing 0.1% glucose at 24 or 37°C. Enzyme activities of the indicated Fe/S cluster-containing proteins and of malate dehydrogenase were measured. DH, dehydrogenase; Succinate cyt c Red, succinate-cytochrome c reductase.
