生物活性測定結果表明該菌株對榆藍葉甲（ pyrrhaltaaenescens （ fairmaire ） ）和光肩星天牛等鞘翅目昆蟲具有較高的毒力，因此初步確認該菌株屬于cry3類； （ 2 ）發現該菌株中編碼毒蛋白的基因位於質粒上，並且已經成功地克隆到該基因。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
且該受體蛋白與cry1ab的結合部位位於bt - r3受體蛋白的胞外結構域。 bt毒蛋白與鈣粘蛋白受體的結合與受體是否糖基化無關。On the temporal and spatial expressions of bt toxin protein in bt transgenic cotton

摘要結合抗人或動物病毒劑，綜述了國內外植物、動物、微生物源的抗植物病毒蛋白、生物堿及抗生素等天然化合物，並對其在防治植物病毒病上的應用進行了展望。Expression of bt toxic protein in transgenic cotton and its ecological effects
毒蛋白的表達及其生態學效應Antiviral protein, avp
抗病毒蛋白[ 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]蓖麻毒素是一種典型的植物毒蛋白，由a 、 b兩條鏈通過二硫鍵結合。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
在得到麻瘋樹毒蛋白cdna序列后，通過pcr對毒蛋白基因進行了克隆，並實現了部分基因片段在大腸桿菌中的高效表達。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
這可能是因為光有這些結構域對結合活性來說是不夠的，還需要其它結構域協同。也有可能bt - r3受體蛋白和bt毒蛋白另有其結合位點。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
表達得到了bt - r3受體的第4 ， 5 ， 6個鈣粘蛋白結構域重組蛋白，其分子量約為42kda和45kda （帶histag ） ，均不能有效地結合bt毒蛋白cry1ab 。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
因為它的毒殺能力強，而且其殺蟲譜又與現在廣泛使用的bt .毒蛋白具有一定的互補性，所以被認為是繼bt .毒蛋白之後的第二代殺蟲蛋白的代表之一。The full - length sequence, the 3 ' - deletion fragment, the sequence encoding the mature protein and the sequence encoding the conservative domain, were cloned using synthesized primers. recombinant expression vectors were constructed through directional cloning and then host e. coli were transformed by the vectors
設計特異引物克隆得到毒蛋白基因的4個片段，即基因全長、末端缺失片段、編碼成熟肽的片段及編碼活性區域的片段。Studies on transformation of indica rice with bt - toxin gene mediated by agrobacterium tumefaciens precultured immature embryo and callus derived from young panicle, immature embryo and mature embryo were used as acceptor for genetic transformation mediated by agrobacterium tumefaciens, the transformation rate of the above acceptor was investigated respectively. the results showed that immature embryo after precultured for 4 ~ 6d was the best. in respect to the concentration of agrobacterium tumefaciens when calli were cotransformated in medium yeb, to agrobacterium tumefaciens eha 105, od value of 0. 8 was the best
