摘要: 利用美国国家生物技术信息中心(NCBI)和瑞士生物信息学研究所的蛋白分析专家系统(ExPASY)中有关基因和蛋白的序列和结构信息分析工具,结合其他生物信息学分析软件包进行分析。牛带绦虫亚洲亚种苹果酸脱氢酶(MDH)基因是全长基因,长度为1 212 bp,编码区为30~1 028 bp,编码332个氨基酸,无跨膜区,具有多个磷酸化位点,蛋白理化性质稳定;预测3个主要的抗原表位(aa95~aa100、aa322~aa327和aa117~aa122)在MDH空间结构上相距较远的分子表面,aa117~aa122属于带绦虫共有的线性抗原表位。预测胞桨型苹果酸脱氢酶是一个潜在的诊断抗原。

Abstract: Tools from bioinformatics websites such as NCBI, ExPaSy were used for the analysis. The malate dehy-drogenase full-length gene from Taenia saginata asiatica was 1 212 bp in length, with a coding region of 30-1 028 bp and coding 332 amino acids. It was a complete and full-length gene compared with the homologues in GenBank. The protein showed no transmembrane region, with stable phycical-chemical characteristics. Three major linear epitopes located aa95-aa100, aa322-aa327 and aa117-aa122, with certain distance from each other on the surface of spatial structure of malate dehydrogenase(MDH). The last one was the linear epitope of Taenia. This cytosolic malate dehydrogenase gene is a potential antigen for diagnosis.
