Peptide, amino acid sequence highly-charged precursor

Transit peptides amino-terminal extensions of precursors to chloroplast proteins which are encoded by nuclear DNA and synthesized in the cytoplasm. The T.p. are removed by Post-translational modification (see) before the protein takes on its mature configuration inside the chloroplast. The overall amino acid sequences of the T.p. are not conserved between species, but the positions of proline and the charged amino acids are highly conserved. The T.p. appear to mediate transport of the chloroplast protein precur-...
