A set of novel heavy-metal complexing peptides was isolated from plant cell suspension cultures; the structure of the peptides was established as (gamma-glutamic acid-cysteine)n-glycine (n = 3 to 7). These peptides appear upon induction of plant cells with heavy metals and represent the principal metal-binding activities in the cells. The name phytochelatin is proposed for this new class of natural products.
从植物细胞悬浮培养物中分离出一组新型重金属络合肽；肽的结构被确定为（γ-谷氨酸-半胱氨酸）n-甘氨酸（n = 3 至 7）。这些肽在重金属诱导植物细胞时出现，代表细胞中主要的金属结合活性。拟为这一类新的天然产物提出植物螯合肽的名称。
