摘要: 以口蹄疫病毒株OA/58 RNA为模板,反转录并扩增目的cDNA,然后与pGEM-T easy载体连接并转化JM109菌株,提取的重组质粒用凝胶电泳、PCR和EcoR Ⅰ酶切法鉴定。运用同源模建得到OA/58 VP1蛋白3D结构,并结合理化性质、亲水性、可塑性和免疫原性进行分析,预测OA/58 VP1的抗原表位。结果 OA/58 VP1存在多个潜在的抗原表位位点,可能的蛋白质抗原表位区域:2~11,15~35,38~50,77~88,90~107,121~125,131~135,10~19,15~163,169~175,178~189,197~213.应用同源模建得到的OA/58 VP1蛋白3D模型来预测其B细胞表位,为进一步研究OA/58 VP1功能,构建突变体和选择表达新型OA/58 VP1蛋白分子提供有参考价值的信息。

Abstract: Foot-and-mouth disease virus strain OA/58 RNAs were used as templates for RTPCR. The amplified cDNA products were cloned into pGEM-T easy vectors and transformed into JM109. The recombinant plasmids were identified by electrophoresis, PCR, and EcoR I cleavage. By means of homology modeling the FMDV strain OA/58 VP1 protein, the 3D mold was obtained. In order to find out B cell epitopes of OA/58 VP1, several methods were analyzed including physical and chemical characters, hydrophilicity, antigenicity. Many distinct antigenic epitopes in FMDV OA/58 VP1 were identified by computation: 2-11, 15-35, 38-50, 77-88, 90-107, 121-125, 131-135, 140-149, 154-163, 169-175, 178-189, 197-213. Application of homology molding OA/58 VP1 to predict B cell epitopes is reasonable. This method offers reasonable information for researching function of OA/58 VP1, constructing its variant body and selecting new expression forms of OA/58 VP1.

Key words: Foot-and-mouth disease virus, VP1 protein, B cell epitope
