A multivalent, bifunctional flagellum carrying two different adhesive peptides in separate flagellin subunits within a filament was constructed in Escherichia coli. The inserted peptides were the fibronectin-binding 115-mer D repeat region of Staphylococcus aureus and the 302-mer collagen-binding region of YadA of Yersinia enterocolitica. Western blotting, immunoelectron microscopy, and adhesion tests with hybrid flagella from an in trans-complemented DeltafliC E. coli strain showed that individual filaments consisted of both recombinant flagellins.
在大肠杆菌中构建了一种多价、双功能鞭毛,该鞭毛在一根丝状体的不同鞭毛蛋白亚基中携带两种不同的粘附肽。插入的肽是金黄色葡萄球菌的纤连蛋白结合115聚体D重复区域和小肠结肠炎耶尔森菌YadA的302聚体胶原结合区域。对来自反式互补的ΔfliC大肠杆菌菌株的杂合鞭毛进行的蛋白质免疫印迹、免疫电子显微镜和粘附试验表明,单个丝状体由两种重组鞭毛蛋白组成。
