HepK, a protein-histidine kinase from the cyanobacterium Anabaena sp. strain PCC 7120, binds sequence-specifically to DNA

Two-component phosphorelay systems are minimally consisted of a sensory protein-histidine kinase (HK) and a response regulator (RR). HK autophosphorylates its conserved histidine residue in response to stimulus from an environment, this phosphate group then is transferred to a conserved aspartic acid residue of an RR, which is generally a transcription factor. HepK is a member… Read More »
