Abstract
|
|
|
|
Effects of organic compounds, photosensitizers and influx of metal ions on the lightinduced mitochondrial ATP synthase in Lentinus edodes purified by stepped sucrose density gradient centrifugation were studied. In our previous work, the activation wavelength and the illumination time of mitochondrial ATP synthase were 470 ㎚ and 15 sec, respectively. This enzyme was activated 85% by 1 mmole 2,6-dichlorophenol indopheol and inhibited by 1 mmole 2,-4-dinitrophenol, 10μmole 2-heptyl-4-hydroxyquinoline-N-oxide and 100㎍ oligomycin per ㎖ of ethanol. Particularly, the enzyme was activated 414% by 10 mmole phenazine methosulfate as photosensitizes at 470 ㎚ light. In the influx effects of Fe^(3+) and Fe^(2+) ion, the activity of the above enzyme increased under the optimal light condition compared with nonillumination state.
