Sensor histidine kinases (SHK) consist of sensor, linker and kinase modules and different models for SHK signal transduction have been proposed. Here the authors present nano- to millisecond time-resolved X-ray scattering measurements, which reveal a structural mechanism for kinase domain activation in SHK.
