Direct detection of Fe(IV)=O intermediates in the cytochrome aa3 oxidase from Paracoccus denitrificans[H2O2 reaction
(2003)We report the first evidence for the formation of the "607- and 580-nm forms" in the cytochrome oxidase aa3/H2O2 reaction without the involvement of tyrosine 280. The pKa of the 607-580-nm transition is 7.5. The 607-nm ...

Fourier transform infrared (FTIR) and step-scan time-resolved FTIR spectroscopies reveal a unique active site in cytochrome caa3 oxidase from Thermus thermophilus
(2002)Fourier transform infrared (FTIR) and step-scan time-resolved FTIR difference spectra are reported for the [carbonmonoxy]cytochrome caa3 from Thermus thermophilus. A major C-O mode of heme a3 at 1958 cm-1 and two minor ...

Interaction of metal complexes with G-quadruplex DNA
(2010)[Figure Presented] Guanine-rich sequences of DNA can assemble into tetrastranded structures known as G-quadruplexes. It has been suggested that these secondary DNA structures could be involved in the regulation of several ...

Nitric-oxide reductase: Structure and properties of the catalytic site from resonance Raman scattering
(2002)We have applied resonance Raman spectroscopy to investigate the properties of the dinuclear center of oxidized, reduced, and NO-bound nitric-oxide reductase from Paracoccus denitrificans. The spectra of the oxidized enzyme ...

Observation of the equilibrium CuB-CO complex and functional implications of the transient heme a3 propionates in cytochrome ba3-CO from Thermus thermophilus. Fourier transform infrared (FTIR) and time-resolved step-scan FTIR studies
(2002)We report the first evidence for the existence of the equilibrium CuB 1+-CO species of CO-bound reduced cytochrome ba3 from Thermus thermophilus at room temperature. The frequency of the C-O stretching mode of CuB 1+-CO ...

Predicting the acid/base behavior of proteins: A constant-pH monte carlo approach with generalized born solvent
(2010)The acid/base properties of proteins are essential in biochemistry, and proton binding is a valuable reporter on electrostatic interactions. We propose a constant-pH Monte Carlo strategy to compute protonation free energies ...

The role of the cross-link His-Tyr in the functional properties of the binuclear center in cytochrome c oxidase
(2002)Resonance Raman and Fourier transform infrared spectroscopies have been used to study the aa3-type cytochrome c oxidase and the Y280H mutant from Paracoccus denitrificans. The stability of the binuclear center in the absence ...

Spin Crossover in Nitrito-Myoglobin as Revealed by Resonance Raman Spectroscopy
(2016)The myoglobin (Mb) heme Fe-O-N=O and heme Fe-O-N=O/2-nitrovinyl species have been characterized by resonance Raman spectroscopy. In the heme Fe-O-N=O species, the bound nitrite ligand is removed by solvent exchange, thus ...
