| 4. | Many studies revealed that pokeweed antiviral protein ( pap ) can control plant virus effectively
许多研究发现美洲商陆抗病毒蛋白( pokeweedantiviralprotein ， pap )对植物病毒具有良好的控制效果。 |
| 5. | [ backgrounds ] many plants produce toxic proteins known as ribosome inactivating proteins ( rips ) whose functions mainly serve as a defensive tool against invasion of other organisms
[目的]蓖麻毒素是一种典型的植物毒蛋白，由a 、 b两条链通过二硫键结合。 |
| 6. | After getting the cdna sequence of curcin , four fragments of the gene were cloned through pcr and high - level expression in e . coli was achieved . the four target dna fragments , i . e
在得到麻疯树毒蛋白cdna序列后，通过pcr对毒蛋白基因进行了克隆，并实现了部分基因片段在大肠杆菌中的高效表达。 |
| 7. | It is possible that only the cadherin repeated domain 4 , 5 , 6 of bt - r3 protein is not enough for bt - r3 protein to bind bt toxic protein , or there is another bind site outside these domains
这可能是因为光有这些结构域对结合活性来说是不够的，还需要其它结构域协同。也有可能bt - r3受体蛋白和bt毒蛋白另有其结合位点。 |
| 8. | Expression system renders products that are free of post - translational modifications , it is likely that the binding of crylab toxin to bt - r3 protein via protein - protein interaction and does not require glycosylation
且该受体蛋白与cry1ab的结合部位位于bt - r3受体蛋白的胞外结构域。 bt毒蛋白与钙粘蛋白受体的结合与受体是否糖基化无关。 |
| 9. | 2 . the molecular weights of the recombinant protein of the cadherin repeated domain 4 , 5 , 6 of bt - r3 were about 42kda and 45kda ( with his tag ) respectively . both expressed products could not specifically bind to bt toxic protein crylab
表达得到了bt - r3受体的第4 ， 5 ， 6个钙粘蛋白结构域重组蛋白，其分子量约为42kda和45kda (带histag ) ，均不能有效地结合bt毒蛋白cry1ab 。 |
| 10. | Because of its high toxity activity and complementary inseticidal spectrum with bt . endotoxin which is now being used universally , the cholesterol oxidase is acknowleged as one of the representitive of the insecticidal protein of the second generation
因为它的毒杀能力强，而且其杀虫谱又与现在广泛使用的bt .毒蛋白具有一定的互补性，所以被认为是继bt .毒蛋白之后的第二代杀虫蛋白的代表之一。 |
