Termination of translation in eukaryotes is governed by two release factors encoded by the SUP45 and SUP35 genes in Saccharomyces cerevisiae. Previously, a set of mutations in these genes had been obtained. However, the exact sequence change associated with one mutation, sup35-222, was not identified by Sanger sequencing of the SUP35 region. Presented here are whole-genome sequencing data for the sup35-222 strain, data on copy number variation in its genome along with supporting pulse-field gel electrophoresis experiment data, and the list of single-nucleotide variations that differentiate this strain and its wild-type ancestor. One substitution upstream the SUP35 gene was located in a sequence corresponding to the Abf1-binding site. Data obtained from the introduction of this variation from sup35-222 strain into a different wild-type strain, specifically, detection of a nonsense-suppressor phenotype accompanied by a decrease in the Sup35 protein level, are also presented in this article.
