摘要(Abstract):
目的用生物信息学技术预测布鲁氏菌Omp10蛋白的抗原表位,寻找布鲁氏菌Omp10的优势表位。方法利用IEDB在线软件、DNAStar软件、Pro Pred MHC Class-ⅡBinding Peptide Prediction Server软件和SYFPEITHI软件,通过分子结构、亲水性、柔韧性、表面可及性以及抗原指数等在线分析Omp10蛋白的二级结构、B细胞抗原表位及T细胞抗原表位。结果布鲁氏菌Omp10蛋白B细胞抗原表位有4个,为26-34、65-75、97-102和115-120氨基酸残基。Omp10蛋白T细胞抗原表位有6个,为64-79、72-87、104-119、6-21、9-24和78-93氨基酸残基。结论通过综合分析布鲁氏菌Omp10蛋白有4个B细胞抗原表位和6个T细胞抗原表位,为进一步筛选具有一定抗原保护性和免疫原性的优势表位和多价疫苗构建奠定了基础。
