The phosphorylation and change in shape of the responder in the E. coli signaling transduction pathway is a key event in signaling because it allows the signal to be transduced to a protein that exists totally within the cell's cytoplasm, amplifies the signal, and allows the altered responder to bind to DNA and stimulate transcription of one or more genes.
