Poly(U)-directed polyphenylalanine synthesis by rat liver ribosomes is strongly inhibited by ricin. Experiments involving hybridization between subunits derived from normal and ricin-treated ribosomes demonstrate that the 60S subunit is the site of action of the toxin. The toxin inactivates the 60S subunit independently of the presence of the 40S subunit.
蓖麻毒素强烈抑制大鼠肝脏核糖体由多聚尿苷酸指导的聚苯丙氨酸合成。涉及来自正常核糖体和经蓖麻毒素处理的核糖体的亚基之间杂交的实验表明,60S亚基是毒素的作用位点。毒素使60S亚基失活,与40S亚基的存在无关。
