摘要
应用SOPMA方法和DNAStar Protean软件综合分析了北京鸭呼肠孤病毒分离株DRV-GZ株的σA、σB蛋白的二级结构、亲水性、表面特性、柔韧性和抗原指数,并对各个蛋白的B细胞抗原表位进行了预测.结果表明,σA蛋白的32~37,56—61,82—85,107~116,128~141,202~207,239—246,256~260,274—280,312~317,381—391和σB蛋白的62~86,117~125,141~163,179~186,270—275,287~289,343~345区域内或附近最有可能是B细胞抗原表位的优势区域.
The secondary structures, hydrophilicity, surface probability plot and antigenic index of protein σA and σB of reovirus strain DRV-GZ from Peking ducks were predicted by the software of SOPMA and DNAStar Protean. Combining the results, the predominant B cell epitopes for σA and σB protein were predicted. The results showed that B cell epitopes of era exist at the sites of 32-37, 56-61, 82-85, 107- 116,128-141,202-207,239-246,256-260,274-280,312-317,381-391 ; B cell epitopes of orb exist at the sites of 62-86, 117-123, 141-163, 179-186, 270-275, 287-289, 343-345.
