Suppression of a nuclear aep2 mutation in Saccharomyces cerevisiae by a base substitution in the 5'-untranslated region of the mitochondrial oli1 gene encoding subunit 9 of ATP synthase.

Abstract excerpt

Mutations in the nuclear AEP2 gene of Saccharomyces generate greatly reduced levels of the mature form of mitochondrial oli1 mRNA, encoding subunit 9 of mitochondrial ATP synthase. A series of mutants was isolated in which the temperature-sensitive phenotype resulting from the aep2-ts1 mutation was suppressed. Three strains were classified as containing a mitochondrial suppressor: these lost the ability to...
