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。
