Thus, it is a good starting place for understanding enzyme dynamics. It is a small ubiquitous enzyme that is well known for changing conformations during its catalytic cycle. These changes occur on the microsecond timescale.ДЄlthough temperature jump spectroscopy could be applied to any number of enzymes, so far IвЂ™ve studied one enzyme in particular, dihydrofolate reductase (DHFR). From this data I can determine the rate at which ligands are binding and unbinding, accompanying enzyme motions, and even conformational changes unrelated to ligand association. However, as a system relaxes to a new equilibrium it will shift in the forward and reverse directions providing information about both processes. Since ligand binding is an exothermic reaction, there will be a net flux of ligands dissociating from the enzyme. The system must relax to a new equilibrium at the higher temperature. Then, a laser pulse is used to rapidly heat a small portion of the sample. The sample starts at equilibrium at a specified temperature.

As determined by the equilibrium constant, some of the ligand is bound and some ligand is free in solution. For example, my samples contain enzymes and ligands. Temperature jump spectroscopy relies on rapidly initiating a change in equilibrium. There are only a few labs around the world that use this technique, and even fewer that use it to study enzymes. To study enzyme dynamics, I use temperature jump spectroscopy.

This means that they physically move, bend, wiggle, and change shape during catalysis. One major aspect that is often overlooked when examining structure-function relationships is that enzymes are dynamic molecules.

While this work is enormously important, it doesnвЂ™t tell the full story. A large portion of the scientific community focuses on determining the structure of enzymes and how the structure impacts function. My research works to fill in the gaps in our knowledge to allow for the efficient development of new enzymes. Conversely, in the case of rational design, we are missing key information for the technique to work at its full potential. Modifying existing enzymes through directed evolution is inefficient and limited by the need for high throughput screening methods. Scientists have made a lot of progress towards creating new enzymes, yet there are still roadblocks. WeВ would be able to create new antibiotics easily to combat antibiotic resistance or to quicklyВ synthesize chemicals for industrial applications. Naturally occurring enzymes are capable of catalyzing a wide variety of reactions, but imagine if we could design an enzyme to catalyze any reaction we wanted. Because enzymes play such an important role in human physiology, they are often targets for drugs and disease treatments. Enzymes are responsible for catalyzing a myriad of reactions necessary for life.
