[The relationship of cytoplasmic and mitochondrial protein synthesis in yeasts: the mapping of mitochondrial mutations neutralizing the exhibition of nuclear omnipotent suppressors].
The genetic and physical mapping of mitochondrial mutations [CRD] neutralizing respiratory deficiency in sup1 and sup2 mutants was performed. The genetical methods demonstrated improbability of location of these mutations in genes coding for the enzymes of respiratory chain and for 21S rRNA. Southern-blot analysis has shown these mutations to be localized in the Hinc10 fragment of mitochondrial genome. This fact was interpreted as indication that var1 gene is affected by [CRD] mutations. Our results are in agreement with the hypothesis on the participation of sup1(2) proteins in mitochondrial translation.
