Catalysis of the phosphorylation of an amino acid residue in a protein, usually according to the reaction: a protein + ATP = a phosphoprotein + ADP. Catalysis of the reaction: ATP + protein L-histidine = ADP + protein phospho-L-histidine. The molecular function that accepts an input of one form and creates an output of a different form. Catalysis of the transfer of a phosphorus-containing group from one compound (donor) to a nitrogenous group (acceptor). Mediates the transfer of a signal from the outside to the inside of a cell by means other than the introduction of the signal molecule itself into the cell. Catalysis of the phosphorylation of a specific transcription regulator in response to the presence of a particular signal substance outside the cell.
