Abrin is one of the potent toxins isolated from the beans of plant abrus precatorius.the toxic protein consists of two disulfide-bonded subunits,the a and b chains.the b chain is a galactose-specific lectin that facilitates the binding of abrin to the cell membrane that precedes endocytosis.after entering the cells,the a chain catalytically inactivates 60s ribosomal subunits by removing adenine position 4324 of 28s r–rna,and thereby inhibits protein biosynthesis.

相思子毒素是从豆科植物(abrus precatorius l。)种子中分离的一种细胞毒性蛋白。它由a，b两条链组成，由一个二硫键相联，b链具有半乳糖凝集活性，可与细胞膜上受体结合，帮助a链进入细胞内，a链进入细胞催化失活60s核糖体亚基，从而使细胞蛋白合成被抑制。
