    • A process of producing a protein of interest in cells of a predetermined plant, comprising: introducing into said cells a vector encoding a fusion protein comprising from the N-terminus to the C-terminus (i) a transit peptide for targeting said fusion protein into plastids and, contiguous thereto, (ii) said protein of interest, wherein the C-terminal three amino acids X−3X−2X−1 of said transit peptide and the N-terminal amino acid Z of said protein of interest form a cleavage site X−3X−2X−1-Z for cleaving said fusion protein between X−1 and Z for releasing said protein of interest in plastids, whereby for a predetermined amino acid Z of said protein of interest an amino acid sequence X−3X−2X−1 is selected from the set of amino acid sequences X−3X−2X−1 naturally occurring contiguous to Z in plastid-targeted fusion proteins in plants, thereby forming said cleavage site.
    • 一种在预定植物的细胞中产生感兴趣的蛋白质的方法,包括:向所述细胞中引入编码包含N末端至C末端的融合蛋白的载体(i)用于靶向所述融合蛋白的转运肽 质体,并且与其相邻,(ii)所述目的蛋白质,其中所述C末端三个氨基酸X-X 1,X 2,X 2, 所述转运肽和所述目的蛋白质的N-末端氨基酸Z的SUP'形成切割位点X-S-X-X, 用于将所述融合蛋白切割在X-1和Z之间,用于释放质体中所述目的蛋白质,由此对于目的蛋白质的预定氨基酸Z,氨基酸序列X < SUP> -3 从集合的氨基酸序列X 3 - 在植物中的质体靶向融合蛋白中与Z邻接天然存在的-2-2个<! - SIPO
