This entry represents an N-terminal domain found in KdpD sensor kinase proteins that regulate the kdpFABC operon responsible for potassium transport [1]. The aligned region corresponds to a cytoplasmic part of the protein which functions as the sensor domain responsible for sensing turgor pressure [2]. It recognises C-di-AMP and K+ [3].	Domain
