Protein Targeting - Sorting of Proteins To Both Chloroplasts and Mitochondria

Sorting of Proteins To Both Chloroplasts and Mitochondria

Many proteins are needed in both mitochondria and chloroplasts. In general the targeting peptide is of intermediate character to the two specific ones. The targeting peptides of these proteins have a high content of basic and hydrophobic amino acids, a low content of negatively charged amino acids. They have a lower content of alanine and a higher content of leucine and phenylalanine. The dual targeted proteins have a more hydrophobic targeting peptide than both mitochondrial and chloroplastic ones.
