LIGHT-INDUCED OXIDATION OF A CHLOROPLAST B-TYPE CYTOCHROME AT -189 degrees C.
The b-type cytochromes of chloroplasts have heretofore been viewed as photosynthetic electron carriers that probably occupy an intermediate position in a light-induced electron flow. The oxidation-reduction of such intermediate electron carriers, being removed from the primary photochemical reaction linked to photon capture by chlorophyll, would be expected to show a temperature dependence. Evi...
متن کاملOxidation of ferrocytochrome c by mitochondrial cytochrome c oxidase.
Attempts to rationalize the kinetics of cytochrome c oxidation catalyzed by solubilized mitochondrial cytochrome c oxidase (ferrocytochrome c:oxygen oxidoreductase, EC 1.9.3.1) have been based on assumptions of productive complex formation (Michaelis-Menten approach). However, the range of substrate concentrations used has not, in general, been sufficient to establish a general rate equation. D...

متن کاملThe oxidation of cytochrome c in nonaqueous solvents.
Cytochrome c was adsorbed readily and remained electroactive, with a redox potential of 32 mV, on TiO2 films placed on SnO2; similar behaviour was observed in glycerol, whereas in acetonitrile, irreversible oxidation occurred at a potential of 800 mV.
متن کاملIncrease in apparent compressibility of cytochrome c upon oxidation.
The apparent molal adiabatic compressibilities of ferri- and ferrocytochrome c have been determined from measurements of density and sound velocity. The values found were +2.99 X 10(-8) and -2.40 X 10(-8) cm5 mol-1 dyne-1 for the ferri and ferro forms, respectively. Experiments were performed on identical solutions containing either the oxidized or reduced form of protein. Solutions of ferricyt...
