Many enzymes contain metalloporphyrins as prosthetic groups, which catalyse a vide variety of biologically important reactions. Hence, these species have been studied by a large number of spectroscopic techniques including Magnetic Circular Dichroism Spectroscopy (MCD). This method is especially useful to investigate the electronic structures and spectra of paramagnetic complexes [1]. However, ...
The nitric oxide synthases are dimeric enzymes in which the intersubunit contacts are formed by the P-450-haem-containing, tetrahydrobiopterin-dependent oxygenase domain. The dimerization of the neuronal isoenzyme was shown previously to be triggered by Fe-protoporphyrin IX (haemin). We report for the first time the reactivation of the haem-deficient neuronal isoenzyme (from rat, expressed in a...
Synthetic and bioinspired metalloporphyrins are a class of redox-active catalysts able to emulate several enzymes such as cytochromes P450, ligninolytic peroxidases, and peroxygenases. Their ability to perform oxidation and degradation of recalcitrant compounds, including aliphatic hydrocarbons, phenolic and non-phenolic aromatic compounds, sulfides, and nitroso-compounds, has been deeply inves...
