Driving force for oxygen-atom transfer by heme-thiolate enzymes.
The heme-thiolate peroxygenase from Agrocybe aegerita (AaeAPO, EC 1.11.2.1) is a versatile biocatalyst and cytochrome P450 analogue which catalyzes a variety of oxygenation reactions with high efficiency and selectivity. Our recent kinetic characterization of AaeAPO-catalyzed reactions has shown that AaeAPO compound I is an oxo-Fe porphyrin radical cation. The reactivity of AaeAPO-I toward a pa...
متن کاملV-A Molecular Mechanisms of Oxygen Activation by Heme Enzymes
A general inability to carry out extensive variations in the electronic characteristics of proximal heme iron ligands in heme proteins has hampered efforts to obtain a clear understanding of the role of the proximal heme iron ligand in the activation of oxygen and peroxide. The disadvantage of the frequently applied site directed mutagenesis technique is that it is limited by the range of natur...
متن کاملCharge effects on oxygen atom transfer.
The rhenium(V) complex [(HCpz3)ReOCl2]+ ([1]+), the tris(pyrazolyl)methane analogue of the known tris(pyrazolyl)borate complex (HBpz3)ReOCl2 (2), has been prepared. The two complexes are strikingly similar, as are the phosphine oxide adducts [(HCpz3)ReCl2(OPPh3)]Cl ([3]Cl) and (HBpz3)ReCl2(OPPh3) (4), which have been characterized by X-ray crystallography. Comparison of the bimolecular reductio...
متن کاملPromotion of oxygen atom transfer in Mo and W enzymes by bicyclic forms of the pterin cofactor.
Density functional theory calculations suggest that bicyclic structures of the "molybdopterin" in DMSO reductases may have an important catalytic role in oxygen atom transfer reactions.
متن کاملDriving Force for Nucleation of Multi-Component Gas Hydrate
Based on driving force for crystallization of one-component gas hydrate, in this report an expression for the supersaturation for crystallization of multicomponent gas hydrate is derived. Expressions for the supersaturation are obtained in isothermal and isobaric regimes. The results obtained are applied to the crystallization of hydrates of mixtures of methane plus ethane and can apply to ...
