Protein oxidation in the intermembrane space of mitochondria is substrate-specific rather than general
March 3, 2014
In this work, the authors suggest that in Saccharomyces cerevisiae, the Mia40-dependent oxidation of proteins in the intermembrane space only takes place in specific proteins and presumably relies on the presence of Mia40-binding sites.

January 29, 2014
This article summarizes recent discoveries in the yeast Saccharomyces cerevisiae model system that point towards a vital role of reversible phosphorylation in regulation of mitochondrial protein import.
