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.
过表达必需泛素连接酶Rsp5或泛素结合酶(Ubc1-Ubc13)的酿酒酵母细胞表现出对各种胁迫的耐受性。Rsp5与Ubc1、Ubc2、Ubc3、Ubc5、Ubc6、Ubc9、Ubc10、Ubc11、Ubc12或Ubc13的共过表达进一步增强了胁迫耐受性。这些结果表明,泛素相关酶的过表达可能是培育新型抗逆菌株的一种有用方法。
