WebOct 1, 2003 · The phosphoryl group is first transferred to an aspartate residue within the receiver domain at the C terminus of the receptor and then from there to a histidine phosphotransfer protein (Hpt), which ultimately phosphorylates and thus activates a response regulator at a central Asp residue 12., 13., 14.. WebExplanation: Two-component signal transduction systems are abundant in cells and mediate the transfer of a single phosphoryl group from a sensor kinase to a response regulator. In contrast, phosphorelay systems are more complex and involve the transfer of multiple phosphoryl groups between a series of proteins. blah blah blah
