| 摘 要： | 植物环肽是一个庞大的小分子天然产物家族，通常由4—10个氨基酸残基组合而成。该类化合物广泛存在于全球多种植物的根、茎、枝、叶及种子中，中草药中也时有发现。由于对其生物合成途径及机理研究较少，环肽分子的利用价值尚未得到有效的开发。和常见的非环状基因编码的多肽或蛋白质相比，环肽结构更为复杂。本文将对植物环肽的生物合成途径及其机理做初步探讨。 |

| Abstract: | Plant cyclopeptides are a large group of small molecular weight natural products, typically with 4 - 10 amino acids, isolated from the leaves, stem barks, roots, and seeds of a wide variety of plant species throughout the world. The peptides are present in many Chinese medicinal plants, and their potentials have not been well exploited because of the lack of knowledge in their biosynthetic origin and mechanism. The cyclopeptides often have complex chemical structures distinct from common polypeptides (proteins) that are non-cyclic and gene-coded. This review discussed the potential origin of the cyclopeptides and their possible biosynthetic mechanisms. |
