The Cry1Ac5 domainⅢhas a distant relationship with other Cry1 proteins and its longβ18-β19 loop possesses a unique tryptophanat residue 544 and a unique asparagineat the loop apex(residue 546),as well as two consecutive serinesfrom residue 547 to 548.Alanine scanning mutations within the loop were initially generated and all mutants could produce bipyramidal crystals and express 130 kDa protoxins.

利用Swiss-Model服务器和Swiss-pdb Viewer软件建立了Cry1Ac5蛋白的三维结构模型,并利用Clustal W和DS ViewerPro软件对比分析了其与其它Cry蛋白之间的差异,发现Cry1Ac5的结构域Ⅲ与其它Cry1蛋白的亲缘关系较远,其结构域Ⅲ上的β18-β19 loop比Cry1Aa、Cry2Aa、Cry3Aa和Cry4Aa蛋白对应的loop长,其组成的残基中色氨酸(W544)、连续的丝氨酸(S547、S548)和loop顶点的天冬酰氨(N546)在Cry蛋白中都是独特的残基分子成分。

When the ratio of starch to sodium chloroacetate is 1:1, the optimal reaction conditions were: microwave radiation time 30 min, addition of 12 mL 96% isopropyl alcohol, CMS with DS 0.7 and solution viscosity of 10000~20000 mPa.s was produced, and better appearance was presented compared with that by dry method.

使用微波辐射作为反应的加热方式,考察了微波辐射时间、碱、溶剂等条件对微波法制备羧甲基淀粉产品取代度和黏度的影响,并最终确定了在微波照射时间为30min,加入96%异丙醇条件下制备出取代度达0.7,黏度在10000~20000mPa.s的产品。

The factors affect on the degree of substitution of product, yield and apparent viscosity, such as the mol rates of EPTAC with -NH2, reaction temperature, reaction time and the content of water in system have been discussed in detail. FTIR spectrometer and UV spectrometer are used to characterize the structure of the derivative and it is proved that substitution reaction mainly occurs on the -N element .The particle size and morphology of chitosan and quantemary ammonium salt of chitosan are analysised by comparing photos of their scanning electron microscope. The degree of substitution of HACC is determined by acid -base conductometric titration. An error in current formula of DS has pointed out and a correct formula has presented.On the base of experience of above experiment, the reaction conditions of HACC were systematically investigated through orthogonal design, and then the best conditions are found. Water-solubility and dependence of pH are studied.
