Abstract

Methods and compositions for rendering proteins directly responsive to an external signal utilizing modulators that themselves respond to the external signal and are associated with the proteins. In response to the external signal, the modulator alters physical properties of the specific protein molecule(s) with which it is associated, thereby altering the structural and functional properties thereof. The modulator may, for example, transfer applied energy to a protein, or to a portion of the protein, thereby changing the protein structure and function.
