title: Enhancement of stress tolerance in Saccharomyces cerevisiae by overexpression of ubiquitin ligase Rsp5 and ubiquitin-conjugating enzymes.
abstract: Yeast Saccharomyces cerevisiae cells overexpressing essential ubiquitin ligase Rsp5 or ubiquitin-conjugating enzymes (Ubc1-Ubc13) showed tolerance to various stresses. Co-overexpression of Rsp5 and Ubc1, Ubc2, Ubc3, Ubc5, Ubc6, Ubc9, Ubc10, Ubc11, Ubc12, or Ubc13 further enhanced stress tolerance. These results suggest that overexpression of ubiquitin-related enzymes might be a useful method for breeding novel stress-resistant strains.
