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。

Using cytochalasin D to prevent global actin from forming filamentous structures, the production of Heliothis armigera nuclear polyhedrosis virus in Hz-AM1 cells grown in the medium containing 0.5μg/ml CD was completely inhibited while its production was reduced to 10〓 in the presence of 0.1μg/ml CD by plaque assay. However, Western blotting revealed that the actin quantity in infected host cells treated or untreated with CD was almost identical. Additionally, CD had no effect on the DNA synthesis of HaNPV.

Western blot表明细胞松弛素D并不影响受染细胞中肌动蛋白的含量，Dot blot表明病毒DNA的合成也没有受到影响，但电子显微镜超薄切片发现在0.5ug／mL细胞松弛素D中形成的病毒粒子形态与正常的有明显区别，认为细胞松弛素D抑制棉铃虫核型多角体病毒的增殖是因为抑制病毒的DNA和蛋白组装成完整有感染性的病毒粒子，即丝状肌动蛋白对病毒粒子的脱壳和DNA的复制、转录没有影响，但对病毒粒子的组装是必须的。
