Understanding Enzymatic C-H Bond Activation: A Combined Spectroscopic and Theoretical Approac
-
Understanding enzymatic C-H bond activation reactions via X-ray absorption and emission spectroscopies of soluble monooxygenases and relevant model complexes
-
Gaining mechanistic and structural insight from enzymes will aid in development of solvent-free, low temperature (120-150 °C) and moderate pressure processes.
-
Using microfluidic mixers and simultaneous X-ray spectroscopy and UV/vis spectroscopy as a way to access protein intermediate states in situ.
