    • Homologs of the E. coli proteins orf353, bacterial lg-like domain (group 1) protein (orf405), flu antigen 43 (orf1 364), NodT-family outer-membrane-factor-lipoprotein efflux transporter (orf1 767), gspK (orf3515), gspJ (orf3516), toriB-dependent siderophore receptor (orO597), fibrial protein (orf3613), upec-948, upec-1232. A chain precursor of the type-1 fimbria! protein (upec-1875), yapH homolog (upec-2820), hemolysin A (recp-3768), and Sel 1 repeat-containing protein (upec-521 1) from several pathogenic strains of E. coli have been identified with regions within the proteins that are conserved across all E. coli. Fragments corresponding to the conserved regions, especially immunogenic fragments such a linear B-epitopes, are provided. In addition, variants of the bacterial lg-like domain (group 1) protein (orf405), yapH homolog (upec2820) and two different fragments of hemolysin A (recp3768) are provided herein that have increased solubility as compared to the native protein where the variants still raise a substantially similar immune response in a subject as the corresponding native protein.
    • 大肠杆菌蛋白质orf353,细菌Ig样结构域(组1)蛋白质(orf405),流感抗原43(orf1 364),NodT家族外膜因子 - 脂蛋白外排转运蛋白(orf1 767),gspK( orf3515),gspJ(orf3516),toriB依赖性铁载体受体(或O597),纤维蛋白(orf3613),upec-948,upec-1232。 1型弗林布的链前体! 已经鉴定了来自几种大肠杆菌致病菌株的蛋白质(upec-1875),yapH同系物(upec-2820),溶血素A(recp-3768)和含Sel1重复序列的蛋白(upec-521 1) 所有大肠杆菌保守的蛋白质。 提供了对应于保守区域的片段,特别是免疫原性片段如线性B-表位。 此外,本文提供的细菌IgG样结构域(组1)蛋白(orf405),yapH同源物(upec2820)和两种不同的溶血素A片段(recp3768)的变体与天然蛋白质相比具有增加的溶解度, 作为相应的天然蛋白质,变体仍然在受试者中引起基本相似的免疫应答。
