Localization of FtsZ in Helicobacter pylori and consequences for cell division.
Of the various kinds of cell division, the most common mode is binary fission, the division of a cell into two morphologically identical daughter cells. However, in the case of asymmetric cell division, Caulobacter crescentus produces two morphologically and functionally distinct cell types. Here, we have studied cell cycle progression of the human pathogen Helicobacter pylori using a functiona...
متن کاملCrystal structure of Helicobacter pylori MinE, a cell division
In Gram-negative bacteria, proper placement of the FtsZ ring, mediated by nucleoid occlusion and the activities of the dynamic oscillating Min proteins MinC, MinD and MinE, is required for correct positioning of the cell division septum. MinE is a topological specificity factor that counters the activity of MinCD division inhibitor at the mid-cell division site. Its structure consists of an ant...
متن کاملMaintenance of the Cell Morphology by MinC in Helicobacter pylori
In the model organism Escherichia coli, Min proteins are involved in regulating the division of septa formation. The computational genome analysis of Helicobacter pylori, a gram-negative microaerophilic bacterium causing gastritis and peptic ulceration, also identified MinC, MinD, and MinE. However, MinC (HP1053) shares a low identity with those of other bacteria and its function in H. pylori r...

Background: Iron deficiency anemia is the most common nutritional disorder in the world. Diet and Helicobacter pylori infection are among the main causes of this disorder. Objective: In this study, the effect of black tea extract and sodium bicarbonate with Helicobacter pylori on the genes involved in iron absorption and storage, as well as cell proliferation, were studied. Methods: Simultane...
