Here we make use of an integrated approach using high-magnetic-field solid-state NMR, X-ray crystallography, and first-principles computation that enables the investigation of enzyme catalysis at a fine level of chemical detail. The X-ray crystal structure provides a coarse framework upon which models of the active site are built using first-principles computational chemistry and various active site chemistries are explored. .
