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 ...

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 ...

Profiling early infection responses: Pseudomonas aeruginosa eludes host defenses by suppressing antimocrobial peptide gene expression
(2005)Insights into the host factors and mechanisms mediating the primary host responses after pathogen presentation remain limited, due in part to the complexity and genetic intractability of host systems. Here, we employ the ...

Time-Resolved Resonance Raman and Time-Resolved Step-Scan FTIR Studies of Nitric Oxide Reductase from Paracoccus denitrificans: Comparison of the Heme b3-FeB Site to That of the Heme-CuB in Oxidases
(2003)Time-resolved resonance Raman (TR3) and time-resolved step-scan (TRS2) FTIR spectroscopies have been used to probe the structural dynamics at the heme b3 proximal and distal sites after carbon monoxide photolysis from fully ...
