Pseudo-wild type revertants from inactive apocytochrome b mutants as a tool for the analysis of the structure/function relationships of the mitochondrial ubiquinol-cytochrome c reductase of Saccharomyces cerevisiae.

Abstract excerpt

We have analyzed the structure/function relationships of the yeast mitochondrial cytochrome b with a new methodology based upon the isolation of pseudo-wild type revertants from well-characterized cytochrome b respiratory deficient mutants. Our goal was to determine how cytochrome b function could be restored in such mutants, at least to some degree, by suppressor mutations within the protein. True wild type...
