Binding Energy and Enzymatic Catalysis
For nearly 100 years, the extraordinary catalytic power of enzymes has fascinated biochemists (1). In a recent article in this Journal, Splittgerber (2) analyzed several ofthe factors by which enzymes are thought to effect catalysis, including proximity and orientation effects, substrate strain, acidbase catalysis, and nucleophilic catalysis. Here we will discuss the fundamental role that the f...
متن کاملX-ray spectroscopy for chemical and energy sciences: the case of heterogeneous catalysis.
Heterogeneous catalysis is the enabling technology for much of the current and future processes relevant for energy conversion and chemicals synthesis. The development of new materials and processes is greatly helped by the understanding of the catalytic process at the molecular level on the macro/micro-kinetic time scale and on that of the actual bond breaking and bond making. The performance ...
متن کاملRelation between enzymic catalysis and energy coupling.
The principles that underlie enzyme catalysis also apply to energy coupling processes. A comparison is made between a kinase system that mediates the phosphorylation of glucose by ATP (hexokinase), as the prototype for enzymic catalysis, and the mitochondrial electron-transfer complexes, as the prototypes for energy coupling systems. Induced polarization of chemical bonds and charge separation ...
متن کاملNanoscale advances in catalysis and energy applications.
In this perspective, we present an overview of nanoscience applications in catalysis, energy conversion, and energy conservation technologies. We discuss how novel physical and chemical properties of nanomaterials can be applied and engineered to meet the advanced material requirements in the new generation of chemical and energy conversion devices. We highlight some of the latest advances in t...
متن کاملCurrent Topics Chemical Basis for Enzyme Catalysis
Some half-century ago Pauling (1, 2) proposed that the lowering of the activation energy in enzyme catalysis stems from the enzyme’s affinity for the transition state exceeding it’s affinity for the substrate. This proposal has great popular appeal and has served as the basis for the design of transition state based inhibitors and for inducing catalytic activity in various molecular templates (...
