The Active Site Structure of Heme a3 3+-C≡N-CuB2+ of Cytochrome aa 3 Oxidase as Revealed from Resonance Raman Scattering
(2003)Resonance Raman and FTIR spectroscopies have been employed to investigate the structure of the heme a3-C≡N-CuB complex of oxidized cytochrome aa3 oxidase. The characterization of this complex is essential since a central ...

Aldoxime dehydratase: Probing the heme environment involved in the synthesis of the carbon-nitrogen triple bond
(2011)Fourier transform infrared (FTIR) spectra, "light" minus "dark" difference FTIR spectra, and time-resolved step-scan (TRS 2) FTIR spectra are reported for carbonmonoxy aldoxime dehydratase. Two C-O modes of heme at 1945 ...

Observation of ligand transfer in ba 3 oxidase from thermus thermophilus: Simultaneous FTIR detection of photolabile heme a 3 2+-CN and transient CuB 2+-CN complexes
(2012)FTIR and light-minus-dark FTIR spectroscopy have been employed to investigate the reaction of oxidized and fully reduced ba3 oxidase with cyanide. The characterization of the structures of the bound CN- in the binuclear ...

Resonance Raman detection of the Fe2+-C-N modes in heme-copper oxidases: A probe of the active site
(2004)Resonance Raman spectroscopy has been employed to investigate the reduced cyano complexes of cytochrome aa3 from bovine heart and Rhodobacter sphaeroides and of cytochrome bo3 from E. coli. In the aa 3-type oxidases, the ...

TG-MS analysis of nitrile butadiene rubber blends (NBR/PVC)
(2011)Blends of nitrile butadiene rubber (NBR) with polyvinyl chloride (PVC) are widely used in products such as hoses and seals. As part of a project that uses NBR/PVC blends for manufacturing forest fire hoses, blends of NBR/PVC ...

Understanding the synergistic catalytic effect between la2O 3 and CaO for the CH4 Lean De-NOx reaction: Kinetic and mechanistic studies
(2005)Doping of La2O3 crystallites with Ca2+ ions significantly enhances the intrinsic rate of NO reduction by CH4 in the presence of 5% O2 at 550°C compared to pure La 2O3 and CaO solids, while the opposite is true after doping ...
