摘    要:为了深入研究猪胸膜肺炎放线杆菌(Actinobacillus pleuropneumonie,App)转铁结合蛋白基因(Transferrin BindingProtein8,脚)的生物学特性,采用生物信息学方法,对GenBank中的5株App的TbpB的核酸及其氨基酸序列进行比对,选取其中的中国湖北分离株(JL03)对其分子结构、理化性质及功能域、蛋白质二级和三级结构等重要参数进行了预测和分析,并在三级结构的基础上进行了同源建模。结果表明,不同APP菌株之间核酸序列相似性较大,而氨基酸序列存在较大差异,二级结构以延伸链和随机卷曲为主要构件,其空间结构与脑膜炎双球菌GNAl870蛋白相似性较高,以此为模板成功构建了三维结构分子模型,为TbpB基因功能的深入研究提供了线索和参考依据。

关 键 词:猪胸膜肺炎放线杆菌  脚B基因  同源建模

Abstract:To lucubrate bionomics of App TbpB,five APP strains were selected from GenBank,analyzed and predicted by the tools of bioinformatics in the following aspects: the composition and alignment of nucleic acid sequences and amino acid sequences,molecular structure,physical and chemical characters,secondary and tertiary structure of protein and so on.The results as following: There were much more similarity in nucleic acid sequences among five APPs than amino acid sequences,extended strand and random coil were ma...
