摘要
目的 预测SARS病毒S蛋白的B细胞表位。方法 基于SARS蛋白基因组序列 ,采用Kyte Doolittle的亲水性方案 ,Emini方案和Jameson Wolf抗原指数方案 ,辅以对S蛋白的二级结构中的柔性区域的分析 ,预测SARS病毒S蛋白的B细胞表位。结果 推测最有可能的B细胞表位位于S蛋白N端第 91～ 98区段、第 112 1～ 115 3区段和第 185～ 193区段内或它们的附近。其它 ,如S蛋白N端第 10 5 0～ 10 5 9、75 2～ 765、41～ 5 0、666～ 674、2 64～ 2 87、3 40～ 3 48、40 8～ 416区段和第 42 4～ 43 9区段内或附近也可能存在B细胞表位。结论 用多参数预测SARS病毒S蛋白的B细胞表位 。
Objective To predict the B cell epitopes for S protein of severe acute respiratory syndrome (SARS) coronavirus. Methods Based on SARS coronavirus genome sequence and the analysis of the flexible regions of secondary structure for S protein, the B cell epitopes for S protein were predicted by methods of Kyte Doolittle hydrophilicity plot, Emini, and Jameson Wolf. Results The computer predicted most possible epitopes for S protein were located within or nearby its N terminal No. 91-98, 1121-1153 and 185-193. The N terminal No. 1050-1059, 752-765, 41-50, 666-674, 264-287, 340-348, 408-416, and 424-439 may be the possible B cell epitopes. Conclusion Prediction of the B cell epitopes for the S protein based on multiple parameters is helpful for the identification of B cell epitopes using experimental methods.
