Homology modeling of 3-D structure of two AChE from L.entomophila were constructed using H.sapiens(1p0i:A) native BuChE structure and Drosophila melanogaster(1d×4:A) native AChE structure as templates,respectively,by SWISS-MODEL.The catalytic triad were found and denoted in the 3-D structure of AChE from L. entomophila referring to T.californica.2.2 Gene cloning ofβ-actin and mRNA expression levels of two AChE genes from L. entomophilaBecause no reference gene has ever been used in Real Time PCR for L.entomophila in GeneBank,a fragment ofβ-actin gene was cloned from L.entomophila(GenBank Accession No.: FJ041117).It consists of 822 bp encoding a protein of 273 amino acids residues.

利用蛋白质结构同源建模工具，分别以人丁酰胆碱酯酶(1p0i：A)和果蝇乙酰胆碱酯酶(1d×4：A)的蛋白晶体结构为模板，对嗜虫书虱2个AChE的三维结构进行同源建模，并在三维结构中发现了AChE的酶解活性位点，证明嗜虫书虱体内也存在2个AChE基因。2.2嗜虫书虱β-actin基因克隆及乙酰胆碱酯酶基因mRNA表达水平研究目前关于嗜虫书虱的分子生物学研究较少，在GenBank中没有可用作内参基因的序列，因此本研究从嗜虫书虱体内克隆获得β—actin基因片段(GenBank登录号：FJ041117)，该片段长度为822 bp，编码273个氨基酸残基，同源性比对分析表明该片段与其它昆虫的β—actin基因具有很高的同源性。

Deoxy-hemoglobin of Bar-Headed Goose was prepared with Na2S2O4 as reducing agent.The single crystals were obtained from polyethylene glycol solution 6000 at pH 7.2, 0.05mool/L phosphate buffer, protein 20mg/ml. Using the hanging drop methed.

报导了以Na2S2O4为还原剂制备脱氧血红蛋白，并以聚乙二醇溶液为沉淀剂，在pH7.2，蛋白浓度20mg／ml条件下培养出适合于X射线分析用的斑头雁脱氧血红蛋白晶体，经X射线平面探测仪收集衍射强度数据和处理。

There are four C-phycocyanin trimers in the asymmetric unit, which associate face-by-face to form two hexamers.

晶体不对称单位中共有四个C-藻蓝蛋白三聚体，它们面对面地紧密聚合成两个六聚体。

Scripps Institute of the United States and his马克耶格尔Professor University of Virginia, the University of Utah colleagues used X-ray crystal photography, the first detailed description of the composition of the HIV virus capsid protein precursors of the hexagonal molecular structure of high-definition, they said hexagonal protein precursors such as CA VI protein oligomers.

美国斯克里普斯研究所的马克。耶格尔教授和他在弗吉尼亚大学、犹他大学的同事一起，采用X光晶体照相术，第一次详细描述了构成HIV病毒衣壳的六边形蛋白体的高清分子结构，他们称这种六边形蛋白体为CA蛋白六聚物。

Additives added products can effectively solve the photolysis of abamectin and Bt crystal protein decomposition by ultraviolet light, can greatly enhance the effect.

产品中添加的助剂能有效解决阿维菌素的光分解和Bt蛋白晶体的受紫外线分解问题，能大大提高产品的防治效果。

Now, in a study that took more than five years to complete, Rockefeller University researchers, in collaboration with a team of bacteriologists at the University of Wisconsin, Madison, have become the first to solve the structure of a protein complex that protects these cells from singlet oxygen.

现在，洛克菲勒大学的研究人员与威斯康星大学的细菌学家一同协作，历经5年多时间的研究，首次获得了一种能够保护细胞免受单态氧损伤的蛋白复合体的晶体结构。

The crystalline body of the enzyme had been attained in the Turku biological technology center, Finland.

由芬兰Turku生物技术中心完成该酶的晶体结晶，为今后该酶三维空间结构的分析和同类型酶蛋白的结晶打下了基础。
