Effector (biology): An effector is a small molecule that binds to a protein and thereby alters the activity of that protein. A modulator molecule binds to a regulatory site during allosteric modulation and allosterically modulates the shape of the protein....

Chemical reaction: A chemical reaction is a process involving one, two or more substances (called reactants), characterized by a chemical change and yielding one or more product(s) which are different from the reactants. Classically, chemical reactions encompass changes that strictly involve the motion of electrons,...
