    • The present invention relates to the function of a polypeptides named HP1122, Cj1464 and PA3351 which are the anti- sigma factor of Helicobacter pylori, Campylobacter jejuni and Pseudomonas aeruginosa, respectively. The present invention also relates to a polypeptide named SID1122 which is the domain of Helicobacter pylori's HP1122 polypeptide involved in a specific interaction with Helicobacter pylori sigma (HP1032) and which has an anti- sigma factor activity. More specifically, the present invention relates to SID1122 polypeptide that interact with HP1032, identification of the HP1032 interacting domain (SID1032) that is specifically involved in the interaction with HP1122, complexes of two polypeptides such as HP1122 HP1032, or SID1122 SID1032, fragments and variants of the SID1122 and SID1032 polypeptides, antibodies to the SID1122 and SID1032 polypeptides, methods for screening drugs or agents which modulate the interaction of Helicobacter pylori's polypeptides encoded by HP1122 and HP1032 and pharmaceutical compositions for treating or preventing Gram negative flagellated bacteria infection in a human or mammal, more specifically Helicobacter sp. or Campylobacter jejuni or Pseudomonas aeruginosa infection, in particular Helicobacter pylori infection in a human or a mammal.
    • 本发明涉及分别作为幽门螺杆菌抗幽门螺杆菌,空肠弯曲杆菌和铜绿假单胞菌的抗HP1122,Cj1464和PA3351的多肽的功能。 本发明还涉及一种称为SID1122的多肽,其是幽门螺杆菌HP1122多肽的参与与幽门螺杆菌σ28(HP1032)的特异性相互作用并且具有抗西格玛28因子活性的结构域。 更具体地,本发明涉及与HP1032相互作用的SID1122多肽,特异性参与与HP1122的相互作用的HP1032相互作用结构域(SID1032)的鉴定,两种多肽如HP1122 HP1032或SID1122 SID1032的复合物,片段和变体 SID1122和SID1032多肽的抗体,SID1122和SID1032多肽的抗体,用于筛选调节由HP1122和HP1032编码的幽门螺杆菌多肽的相互作用的药物或药剂的方法和用于治疗或预防人类革兰氏阴性鞭毛细菌感染的药物组合物, 哺乳动物,更具体地说是幽门螺杆菌 或空肠弯曲杆菌或铜绿假单胞菌感染,特别是人或哺乳动物的幽门螺杆菌感染。
