Isolation and characterization of an uncoupler-resistant mutant of Saccharomyces cerevisiae

One mutant resistant to carbonylcyanide m-chlorophenylhydrazone (CCCP), an uncoupler of oxidative phosphorylation, was isolated in Saccharomyces cerevisiae. Genetic analysis showed that a single nuclear gene is responsible for increased resistance; this gene was dominant. The mutant showed cross-resistance or collateral sensitivity to several chemically… (More)
