If you wanted to improve the catalytic efficiency of an enzyme, would you mutate amino acid residues to increase/decrease binding affinity for the substrate, or to increase/decrease the binding of the transition state? Explain. Mutate amino acids to increase binding to the transition state because it increases the activation energy; mutations that bind substrate more tightly decrease the activation energy. Mutate amino acids to decrease binding to the transition state because it increases the activation energy; mutations that bind substrate more tightly decrease the activation energy. Mutate amino acids to increase binding to the transition state because it decreases the activation energy; mutations that bind substrate more tightly increase the activation energy. Mutate amino acids to increase binding to the substrate bind because it decreases the activation energy; mutations that bind the transition state more tightly increase the activation energy.
