Figure 4From: A novel mutant of the Sup35 protein of Saccharomyces cerevisiae defective in translation termination and in GTPase activity still supports cell viabilityFull-length T341D compromise viability whereas the C-terminal T341D does not. Both full-length and C-terminal T341A are compatible with viability. The strain deleted for endogenous SUP35 and rescued by an URA3 plasmid containing the wild-type SUP35 gene was transformed with either pRS313-SUP35, pRS313-SUP35A, pRS313-SUP35D (HIS3 plasmids) or with pFL36-SUP35cter, pFL36-SUP35Acter and pFL36-SUP35Dcter (LEU2 plasmids). Transformants were streaked onto 5FOA to eliminate the URA3 plasmid containing the wild-type copy of SUP35.Back to article page
