virB11 gene potentially involves in ATP metabolism to provide energy in H. pylori infection

In this study, the structure and biology of virB11 gene were analyzed and elucidated with bioinformatics analysis. After cloning, expression and purification, VirB11 protein was generated for the cytotoxicity to GES-1 cells and the anti-VirB11 protein antibody production for localization and interaction proteins analysis. The results showed that VirB11 protein is a hydrophilic protein, mainly locates in cell membrane. IL-8 productions from GES-1 cells co-culture with VirB11 protein were increased gradually with time (p < 0.001). The interaction proteins of VirB11 protein were F0F1 ATP synthase subunit alpha, ATP synthase subunit beta and isocitrate dehydrogenase. We demonstrate that VirB11 protein possesses cytotoxicity and potentially plays important roles in ATP metabolism to provide energy in the course of H. pylori infection.
