Abstract: | Genes SUP35 and SUP45 have been identified in the saccharomycete yeast as genes controlling termination of translation in cytoplasmic ribosomes. However, many facts indicate that the control of translation termination is not the only function of these genes. This work is devoted to studying one of the pleiotropic effects of sup35 and sup45 mutations, a respiratory deficiency. The compensation for this deficiency in mutants for either gene can occur due to a mutation in the ATP17 gene encoding the f-subunit of mitochondrial F1F0 ATP synthase. It is assumed that the observed interaction can be related to the system of co-translational protein import into mitochondria. |
