ABSTRACT We present the crystal structure of the extracytoplasmic domain of the Bacillus subtilis PhoR sensor histidine kinase, part of a two-component system involved in adaptation to low environmental phosphate concentrations. In addition to the PhoR structure, we predict that the majority of the extracytoplasmic domains of B. subtilis sensor kinases will adopt a fold similar to the ubiquitous PAS domain.

The ?2-component? regulatory systems of bacteria are the predominant signal transduction mechanisms that bacteria utilise to modulate behaviours and metabolism in response to environmental changes. These systems classically involve two proteins ? a membrane bound sensor histidine kinase and a soluble response regulator.

ABSTRACT YycI and YycH are two membrane-anchored periplasmic proteins that regulate the essential Bacillus subtilis YycG histidine kinase through direct interaction. Here we present the crystal structure of YycI at a 2.9-Å resolution. YycI forms a dimer, and remarkably the structure resembles that of the two C-terminal domains of YycH despite nearly undetectable sequence homology (10%) between the two proteins.
