Previous investigations of nitrite and nitric oxide reduction by myoglobin in surfactant film modified electrodes characterized several distinct steps in the denitrification pathway, including isolation of a nitroxyl adduct similar to that proposed i

The EXAFS and resonance Raman spectra on the HNO-myoglobin adduct, 1, are consistent with the presence of HNO bound to a heme center. The three-dimensional structure about the heme center of 1 obtained from multiple-scattering (MS) analysis of the EX

We report the synthesis and characterization of RuC7, a complex in which a heme is covalently attached to a [Ru(bpy)_3]^(2+) complex through a −(CH_2)_7− linker. Insertion of RuC7 into horse heart apomyoglobin gives RuC7Mb, a Ru(heme)−protein c

Nitrosyl hydride, HNO, also commonly termed nitroxyl, is a transient species that has been implicated in the biological activity of nitric oxide, NO. Herein, we report the first generation of a stable HNO-metal complex by direct trapping of free HNO.

The surfactant film methodology is used to examine the electrochemistry of manganese-substituted myoglobin. Cyclic voltammograms at different scan rates depict a dynamic exchange between two redox couples, E1 (-0.25 V vs. SCE) and E2 (-0.41 V). Simil

The photolysis of the HNO-myoglobin adduct has been followed by transient absorption experiments down to the nanosecond time scale. A unique transient assignable to generation of an FeIII/HNO- geminate pair is observed; the transient loss of this abs
