Sorting of Proteins To Chloroplasts
The preprotein for chloroplasts may contain a stromal import sequence or a stromal and thylakoid targeting sequence. The majority of preproteins are translocated through the Toc and Tic complexes located within the chloroplast envelope. In the stroma the stromal import sequence is cleaved off and folding as well as intra-chloroplast sorting to thylakoids continues. Proteins targeted to the envelope of chloroplasts usually lack cleavable sorting sequence.

Famous quotes containing the word proteins:
“Civilization means food and literature all round. Beefsteaks and fiction magazines for all. First-class proteins for the body, fourth-class love-stories for the spirit.”
—Aldous Huxley (1894–1963)
