[Mysteries of mitochondrial protein synthesis].
Mitochondria possess an endogenous system of translation, in which all constituent components are unique. An electrophoretic analysis of mitochondrial translation products revealed that the content of polypeptides in mitochondria is two times as high as that of mitochondrial DNA genes. The electrophoretically determined molecular mass of proteins synthesized in mitochondria is much less than that calculated from gene sequencing data. The average amino acid composition of the proteins synthesized in mitochondria differs significantly from that encoded by the nucleotide sequence of corresponding mitochondrial genes. These enigmas of mitochondrial protein synthesis await further solution.
