The mechanism of dual targeting of proteins to mitochondria and chloroplasts is poorly understood.
The interaction between a dually targeted peptide and the chloroplastic receptor Toc34 was examined.
The interaction between AtThrRS-dTP(2–60) and AtToc34 involves residues throughout the entire targeting peptide sequence.
The interaction of AtThrRS-dTP(2–60) with AtToc34 is different to the interaction with AtTom20.
