Abstract

Background: The mitochondrial sulfhydryl oxidase Erv1 is implicated in cytosolic iron-sulfur protein maturation and iron regulation.

Results: An erv1 yeast strain used in previous iron metabolism studies is glutathione-deficient, and erv1/mia40 mutants with sufficient glutathione do not exhibit iron-related defects.

Conclusion: Iron homeostasis is independent of Erv1/Mia40 function. Significance: The unexplained role of Erv1 in yeast iron metabolism is resolved.
