Figure 3.

Amino acid sequences of identified CPE cleavage sites. The processing sites of preRBCA (Spinacia oleracea)(10), preLHCPI (Lycopersicon esculentum)(43), preLHCPII (Triticum aestivum)(15), preOEE1 (T. aestivum)(44), preOEE2 (T. aestivum)(45) and prePC (Silene pratensis)(19) are shown. The amino acids found by N-terminal sequencing of the cleavage product of preRBCA generated by immobilized CPE-B are underlined. The length of the precursors is noted in parentheses. Position of the C-terminal amino acids of the transit peptides is shown. The cleavage sites are indicated by arrows.
