丝瓜和苦瓜核糖体失活蛋白的比较研究

Research in the Comparison of Ribosome-inactivating Protein between Luffa Cylindrica and Momordica Charantia Linn

从丝瓜和苦瓜种子中分离得到的丝瓜子和苦瓜子蛋白 ,均是含糖的单链核糖体失活蛋白 ,等电点在 9～ 10之间 ,在抑制蛋白质合成中丝瓜子蛋白的毒性高 ,而在抗生育活性中 ,苦瓜子蛋白较好 .

The Luffin and Momorcharin separated from seeds of Luffa and Momordica charantia linn are both single-chain ribosome-inactivating protein with sugar. In inhibiting the formation of protein the toxicity of Luffin is stronger while in the activation of anti-breeding, Momorcharin is better.
