The two-component phosphorylation network is of critical importance for bacterial growth and physiology. Here, we address plasticity and interconnection of distinct signal transduction pathways within this network. In Caulobacter crescentus antagonistic activities of the PleC phosphatase and DivJ kinase localized at opposite cell poles control the(More)
The redox protein flavodoxin has been shown earlier to be reduced by the pyruvate-oxidoreductase (POR) enzyme complex of Helicobacter pylori, and also was proposed to be involved in the pathogenesis of gastric mucosa-associated lymphoid-tissue lymphoma (MALToma). Here, we report its X-ray structure, which is similar to flavodoxins of other bacteria and(More)
