Oscillatory Active-site Motions Correlate with Kinetic Isotope Effects in Formate Dehydrogenase
{{output}}
Thermal motions of enzymes have been invoked to explain the temperature dependence of kinetic isotope effects (KIE) in enzyme-catalyzed hydride transfers. Formate dehydrogenase (FDH) from Candida boidinii exhibits a temperature independent KIE that becomes tem... ...
