Thought Review

There are four dominant methods of chemical catalysis that occur in biological systems. 

You should be able to select an example of each and discuss in terms of the potential energy surface the forces involved in the catalytic mechanism. 

1 kcatIKM. Chymotrypsin = 2 x 10 Carbonic anhydrase = 7.5 x 10 Catalase = 3.89 x 10 Penicillinase = 4 x 10 Lysozyme = 8.33 X 10 . Diffusion is the most likely limiting factor for Cai bonic anhydrase, Catalase, and Penicillinase because their KciaIKm is on the order of 10 Chymotrypsin and lysozyme are most likely limited by something other than diffusion. 

3 The Arrhenius equation can be used to solve the change in this case. 

The relative rate of the highest activation energy reaction (c) increases substantially more than the lowest activation energy (b) because the rate is negligible in (c), so any increase in temperature results in a relatively large change, while low activation energy reactions have appreciable rates that are only increased a little with a small increase in temperature.

The choice of assays or biomarkers that are used for assessing the safety of protein scaffold therapeutics should only be made after careful and thoughtful review. Specialized testing should be conducted for the scaffold or pharmacophore only after careful consideration has been given to the chemical structures and/or potential physiologic or pharmacologic actions.

Summary. Although the preceding examples of transient RR and TR studies of Hb structural dynamics provide an introduction to these issues, detailed structural interpretation and the precise temporal behavior of the various modes are quite complex and obviously beyond the scope of this introductory review. Rousseau and Friedman have provided a comprehensive and thoughtful review of most of these studies. In addition, TR studies which extend the temporal resolution to the subpicosecond regime have now appeared" and have also been reviewed elsewhere. These are essential reading to gain a clearer picture of Hb structural dynamics.
