Xiaoshi Wang receives Springer Theses Award

Recent graduate Xiaoshi Wang (Groves Lab) has been awarded the prestigious Springer Theses Award for her thesis entitled “A Novel Heme-Thiolate Peroxygenase AaeAPO and Its Implications for C-H Activation Chemistry.”
 
Xiaoshi was nominated by her Thesis Advisory Committee member, Prof. Seyedsayamdost who shared the following recommendation, “In her thesis, Xiaoshi examined the mechanism of action of a new extracellular heme-thiolate P450 peroxygenase. P450 enzymes are versatile catalysts that carry out a number of important and difficult modifications. For decades, the application of this enzyme class in the industry has been a major goal; however, their instability and lack of solubility has precluded wide-spread industrial use. Xiaoshi's thesis focused on an extracellular P450 enzyme that does not have many of these limitations. In her thesis she demonstrates that the peroxygenase catalyzes a wide scope of reactions, in some cases very difficult transformations in molecules that are highly inert. Her detailed investigations provide a mechanistic framework for how the peroxygenase catalyzes this wide array of reactions. A major highlight of her thesis is the identifications of key short-lived intermediates in the catalytic cycle of the peroxygenase, using rapid kinetic and spectroscopic methods, as well as elucidation of the thermodynamic properties of these high-energy intermediates. Heme-thiolate P450 enzymes have been studied for over 40 years, yet the thermodynamic information gathered on the peroxygenase by Xiaoshi is a major ‘first’. Her work adds new insight into an important class of enzymes and deserves the strongest consideration for the award.”
