Biochemical and structural studies on metal sensing and acquisition in Bacillus subtilis

Subject Area Metabolism, Biochemistry and Genetics of Microorganisms
Term from 2008 to 2011
Project identifier Deutsche Forschungsgemeinschaft (DFG) - Project number 70287000
 
In this research proposal we will investigate the molecular mechanisms and the structuralaspects underlying iron and copper sensing as well as acquisition in B. subtilis. During ironstarvation, B. subtilis secretes the catecholic trilactone siderophore bacillibactin, whosesecretion mechanism by YmfE and Mta, iron-dependent uptake by the FeuABC-YusVtransporter, its intracellular sensing by the regulatory protein YbbB and iron release by theesterases BesA/YbbA will be studied. In addition, we will genetically and biochemicallycharacterize the unknown intracellular iron and copper channelling components as well as theputative copper-sensing YvgZ protein.
