Abstract
Only five mitochondrial proteins are known to be essential for viability of the yeast Saccharomyces cerevisiae; all of them are key components of the mitochondrial protein import system. Other components of this system are not essential for life; they include functionally redundant import receptors on the mitochondrial surface and enzymes acting upon only a few precursor proteins.
