Structural analysis of chloroplast transit peptides (cTPs), including secondary structure prediction and analysis of 'cTP-like' peptides of known 3D structure, suggests that cTPs are essentially flexible peptides devoid of regular secondary or tertiary structure. It is proposed that cTPs may be designed to interact with a succession of different chaperones on the chloroplast protein-import pathway.
叶绿体转运肽（cTPs）的结构分析，包括二级结构预测和对已知三维结构的“类cTP”肽的分析，表明cTPs本质上是缺乏规则二级或三级结构的柔性肽。有人提出，cTPs可能被设计用于在叶绿体蛋白质导入途径上与一系列不同的分子伴侣相互作用。
