“…5B). To exaggerate the growth defect in the pic2⌬ strain, we transformed the cells with a matrix-targeted copper metallothionein (CRS5) that we have used previously to biochemically deplete the bioavailable matrix copper pool (14). The pic2⌬ strain expressing matrix-targeted CRS5 exhibited a greater growth defect compared with the pic2⌬ strain alone on copper-replete non-fermentable medium, a defect that became more severe upon depletion of available copper from the medium by addition of increasing BCS concentrations (Fig.…”

“…To monitor mitochondrial copper homeostasis without confounding factors related to translation or the activity of other chaperone proteins, we used the previously described copper/ IMS biomarker strain (14). In this biomarker strain, the gene for the copper chaperone for Sod1, CCS1, has been deleted, rendering the yeast Sod1 inactive and causing a lysine auxotrophy.…”

“…Le cuivre présent dans la matrice correspond à ~85 % du cuivre mitochondrial. Dans la matrice, le cuivre serait lié à un ligand inconnu non-protéique de faible masse molé-culaire [29]. Le pool de cuivre pourrait agir comme source pour les cuproprotéines de l'IMS.…”
