Lack of SOD1 in a RAD51 mutant depending on CCS1 exacerbates genomic instability and oxidative stress-mediated cytotoxicity in Saccharomyces cerevisiae.
Title: Lack of superoxide dismutase in a rad51 mutant exacerbates genomic instability and oxidative stress-mediated cytotoxicity in Saccharomyces cerevisiae.
propose a complete molecular mechanism for CCS1 activity and reclassification as a first-of-its-kind "dual chaperone."
Title: The yeast copper chaperone for copper-zinc superoxide dismutase (CCS1) is a multifunctional chaperone promoting all levels of SOD1 maturation.
Data suggest that Ccs1 activates immature Sod1 by delivering copper and facilitating oxidation of intramolecular disulfide bond in Sod1; Ccs1 binding exposes an electropositive cavity and proposed "entry site" for copper ion delivery on the apoenzyme. (Ccs1 = copper chaperone for superoxide dismutase; Sod1 = copper-zinc superoxide dismutase)
Title: Copper-zinc superoxide dismutase is activated through a sulfenic acid intermediate at a copper ion entry site.
Data show that the aging process increased the DNA damage rates 3-fold in the wild type and more than 5-fold in superoxide dismutases sod1Delta, sod2Delta, and molecular chaperone ccs1Delta mutant cells.
Title: Absence of superoxide dismutase activity causes nuclear DNA fragmentation during the aging process.
CCS-dependent copper acquisition and distribution largely occur at membrane interfaces and that this emerging role of the bilayer may reflect a general mechanistic aspect of cellular transition metal ion acquisition.
Title: Cellular distribution of copper to superoxide dismutase involves scaffolding by membranes.
Localization of the reduced, Ccs1-independent forms of Sod1 relied on Mia40, an essential component of the mitochondrial intermembrane space import and assembly pathway
Title: Mia40 and MINOS act in parallel with Ccs1 in the biogenesis of mitochondrial Sod1.
The Mia40/Erv1 disulfide relay system introduces a structural disulfide bond in the copper chaperone Ccs1 between the cysteine residues C27 and C64, thereby promoting mitochondrial import of this unconventional substrate.
Title: Mitochondrial Ccs1 contains a structural disulfide bond crucial for the import of this unconventional substrate by the disulfide relay system.
The oxidoreductase of the mitochondrial disulfide relay, Mia40, controls oxidative folding of domain I of the copper chaperone Ccs1 whereby controlling the cellular distribution of Ccs1 and, consequently, active Superoxide dismutase 1 (Sod1).
Title: Mia40-dependent oxidation of cysteines in domain I of Ccs1 controls its distribution between mitochondria and the cytosol.
Results describe the identification of the copper chaperone for superoxide dismutase as a mediator of copper delivery to XIAP in cells.
Title: Regulation of the copper chaperone CCS by XIAP-mediated ubiquitination.
