Abstract
The N-termini of 4 mitochondrial translation products, the var 1 protein, cytochrome b and subunits I and III of cytochrome C oxidase were characterized in S. cerevisiae and compared with the known DNA sequences of the respective structural genes. The 4 mature proteins correspond to the predicted primary translation products and retain the formylated methionine residue. Thus, subunit II of cytochrome C oxidase studied previously is so far the only mitochondrial translation product carrying a N-terminal-extended transient presequence in S. cerevisiae.
