✦ Synopsis


A polypeptide chain-terminating mutation (M5631) previously has been shown to be a +1T insertion in the yeast mitochondrial gene oxi1, coding for subunit II of the cytochrome c oxidase. A spontaneously arisen frameshift suppressor (mfs-1) that is mitochondrially inherited suppresses this mutation to a considerable extent. The suppressor mutation was mapped by genetic and molecular analyses in the mitochondrial tRNASer-var1 region of the mitochondrial genome of the yeast S. cerevisiae. Genetic analyses show that the suppressor mfs-1 does not suppress other known mitochondrial frameshift mutations, or missense and nonsense mutations.

The first case of a +1 "extrageneic" frameshift suppressor (MF1), mapping in the yeast mitochondrial 15S rRNA gene is reported. The suppressor was identified by genetic analyses in a leaky mitochondrial oxil frameshift mutant and the respective wild-type strain 777-3A of the yeast S. cerevisiae. Thi

A physical map of the COB region in mtDNA of yeast has been established. This region harbours a split gene coding for apocytochrome b. It includes restriction sites of seven endonucleases (EcoRI, HindII, HindIII, HaeIII, HpaII, AluI and BamHI). Various mtDNA sequences of this region, retained in a s
