“Insight into the Reactivity of Pterin-containing Mo Enzyme Models”
Pterin containing molybdenum enzymes provide vitality to life processes. Without these enzymes, no phyla of life can sustain. These enzymes catalyze reactions that are important in global cycling of C, N, S, As and Se. In general, the substrate transformation involves transfer of an oxygen atom with concomitant transfer of two electrons. Such oxygen atom transfer (OAT) reactions are also important in industrial processes such as epoxidation of olefins. Using suitable model compounds, we have probed details of reactivity of these molecules. Mass spectrometry has played a pivotal role in deciphering the details. This work led to a two-step process for oxygen atom transfer reactions, and the rate limiting steps can be altered via molecular design. This talk will highlight the use of mass spectrometry in developing an understanding of this fundamental reactivity and dynamics of molybdenum complexes.
