Figure 1From: Viable nonsense mutants for the essential gene SUP45 of Saccharomyces cerevisiaeSchematic representation of sup45-n mutations isolated in present work. Position of the mutations is indicated above the SUP45 gene. The numbers under the SUP45 gene correspond to amino acid positions whose codons were changed to premature stop codons. Numbers on the right of arrows correspond to the size of truncated eRF1 protein.Back to article page
