摘要

采用生物信息学软件GenBank数据库、PDB数据库、Immunomedicine Group、Bepipred-2.0 server、ABCpred、NetMHCⅡpan 4.0 Serer、SYFPEITHI、NetMHC和NetCTL在线工具分析鸡蛋过敏原溶菌酶Gal d 4的一级氨基酸序列、二级结构并预测其B细胞线性表位和T细胞表位。利用溶菌酶三级结构空间模型,对预测的线性表位进行定位。同时,利用鸡蛋过敏患者血清对Gal d 4的B细胞线性表位进行鉴定。结果表明,3种生物信息学软件预测的5个相同潜在B细胞线性表位为:19KVFGRCELAAAMKR32、57NTQA60、65TDG67、87TPGSRNLCNI96和132RCKGTDVQAWI142。此外发现,19KVFGRCELAAAMKR32、57NTQA60和132RCKGTDVQAWI142、65TDG67和87TPGSRNLCNI96在氨基酸序列上不连续,却在空间结构上邻近,因此,这部分线性表位可能共同构成构象表位。预测所得2个T细胞抗原表位分别为:42SLGNWVCAA50和100ALLSSDITA108。经鉴定所得具有免疫活性的B细胞线性表位为:19KVFGRCELAAAMKR32。该研究首次对鸡蛋过敏原Gal d 4的B细胞线性表位和T细胞表位预测定位及鉴定,有助于进一步认识鸡蛋过敏原Gal d 4的功能与结构,对鸡蛋过敏原的识别与检测具有重要的参考与借鉴作用。

Abstract

This study aimed to analyze the primary amino acid sequence, secondary structure to predict the B cell linear epitopes and T cell epitopes of Gal d 4 by bioinformatics software (GenBank database, PDB database, Immunomedicine Group, Bepipred-2.0 Server, ABCpred, NetMHCⅡpan 4.0 Serer, SYFPEITHI, NetMHC, and NetCTLonline tools), and the study also positioned the linear epitopes on the spatial model of lysozyme tertiary structure. The linear B cell epitopes of Gal d 4 were identified by serum of patients. esults showed that the same B cell linear epitopes predicted by the three bioinformatics software were 19KVFGRCELAAAMKR32,57NTQA60,65TDG67,87TPGSRNLCNI96, and 132RCKGTDVQAWI142. In addition, 19KVFGRCELAAAMKR32,57NTQA60 and 132RCKGTDVQAWI142,65TDG67 and 87TPGSRNLCNI96 were discontinuous in amino acid sequence, but adjacent in spatial structure, which made them have the potential to form conformational epitopes. The predicted T cell epitopes were 42SLGNWVCAA50 and 100ALLSSDITA108. The linear B cell epitope immunoreactivity was identified as 19KVFGRCELAAAMKR32. This study was the first to predict the linear B cell epitopes and T cell epitopes of Gal d 4. The prediction of linear epitopes of Gal d 4 will be helpful to further understand the function and structure of Gal d 4 and will provide important reference for the identification and detection of egg allergens.

Key words： egg allergen; lysozyme; bioinformatics; B cell linear epitopes; T cell epitopes
