Journal ArticleDOI
One-electron-transfer reactions in biochemical systems. V. Difference in the mechanism of quinone reduction by the NADH dehydrogenase and the NAD(P)H dehydrogenase (DT-diaphorase).
Takashi Iyanagi,Isao Yamazaki +1 more
TL;DR: It is concluded that the reduction of quinones and oxygen by flavoproteins falls into three mechanistic categories: one-electron, two-Electron and mixed-type reactions.
Journal ArticleDOI
Oxidation states of peroxidase.
Isao Yamazaki,Ken-nosuke Yokota +1 more
TL;DR: Five oxidation states of horseradish peroxidase, ferrous, ferric, Compounds I and II, oxy-ferrous, are known.
Journal ArticleDOI
Preparation of crystalline oxymyoglobin from horse heart.
TL;DR: This communication deals with procedures for the isolation of native oxy myoglobin from fresh horse heart, and the chromatographic separation of oxymyoglobin from metmyoglobin with diethylaminoethyl cellulose.
Journal ArticleDOI
One-electron-transfer reactions in biochemical systems III. One-electron reduction of quinones by microsomal flavin enzymes
Takashi Iyanagi,Isao Yamazaki +1 more
TL;DR: Electron transfer from reduced cytochrome b 5 reductase to monodehydroascorbate occurs at a considerable rate and is investigated quantitatively with electron spin resonance spectroscopy.
Journal ArticleDOI
Analysis and computer simulation of aerobic oxidation of reduced nicotinamide adenine dinucleotide catalyzed by horseradish peroxidase.
Kennosuke Yokota,Isao Yamazaki +1 more
TL;DR: Time courses of NADH oxidation, O2 consumption, H2O2 accumulation, and formation of enzyme intermediates could be simulated with an electronic computer using 11 elementary reactions and 9 rate equations to discuss the mechanism for oscillatory responses of the reaction.
