Pulse radiolysis studies on superoxide reductase from Treponema pallidum.
Superoxide reductases (SORs) are small metalloenzymes, which catalyze reduction of O2*- to H2O2. The reaction of the enzyme from Treponema pallidum with superoxide was studied by pulse radiolysis methods. The first step is an extremely fast bi-molecular reaction of the ferrous center with O2, with a rate constant of 6 x 10 (8) M(-1) s(-1). A first intermediate is formed which is converted to a ...
متن کاملIsir Subpicosecond Pulse Radiolysis System
The highest time resolution of the pulse radiolysis had remained about 30 ps since the late 1960’s. To make clear the primary processes in the radiation chemistry and physics within 30 ps, we developed a stroboscopic pulse radiolysis system for the absorption spectroscopy with the time resolution of 2.0 ps (10-90% rise time). The time resolution of 2.0 ps was estimated from the time-dependent b...
متن کاملPulse radiolysis of aqueous thiocyanate solution.
The pulse radiolysis of N(2)O saturated aqueous solutions of KSCN was studied under neutral pH conditions. The observed optical absorption spectrum of the SCN(*) radical in solution is more complex than previously reported, but it is in good agreement with that measured in the gas phase. Kinetic traces at 330 and 472 nm corresponding to SCN(*) and (SCN)(2)(*-), respectively, were fit using a Mo...
متن کاملDevelopment of Double-decker Electron Beam Accelerator for Femto/attosecond Pulse Radiolysis
A concept of double-decker electron beams, which have vertically different positions and time delay, was proposed for study of ultra-fast electron-induced reactions or phenomena by pulse radiolysis technique. One of the double-decker electron beams is used as a pump source, and another is converted to Cherenkov light and used as a probe light source. The double-decker electron beams were genera...
متن کاملElectron transfer in milk xanthine oxidase as studied by pulse radiolysis.
Electron transfer within milk xanthine oxidase has been examined by the technique of pulse radiolysis. Radiolytically generated N-methylnicotinamide radical or 5-deazalumiflavin radical has been used to rapidly and selectively introduce reducing equivalents into the enzyme so that subsequent equilibration among the four redox-active centers of the enzyme (a molybdenum center, two iron-sulfur ce...
