Abstract

Bacterial cells often use two-component signal transduction systems to regulate genes in response to environmental stimuli. The RstA/RstB system is a two-component regulatory system consisting of the membrane sensor, RstB, and its cognate response regulator RstA. The RstA of Klebsiella pneumoniae consists of a N-terminal receiver domain (NRD, residues 1-119) and a C-terminal DNA-binding domain (DBD, residues 130-236). Phosphorylation of the response regulator induces a conformational change in the regulatory domain of RstA, which results in activation of the effector domain to regulate the downstream genes, including the ferrous iron transport system (Feo), at low-pH condition. Here we report the 1H, 13C and 15N resonance assignments and secondary structure identification of the DBD of RstA from K. pneumoniae as a first step for unraveling the structural and functional relationship of the RstA/RstB two component system.
