|
Effects of organic compound, photosensitizer and K^+ ion influx. On the light-induced ATPase of mitochondria in L. edodes purified by linear sucrose density gradient centrifugation were studied. The mitochondrial ATPase activity was investigated by various wavelength illumination at dark state. The mitochondrial ATPase was activated 139 and 128 by 10m ㏖ dithiothreitol and 0.1m ㏖ quinacrine, respectively. This enzyme also was activated 36% by 0.1m ㏖ phenazine methosulfate as photosenaitizer. But, 100 ㎎ oligomycin and 1m ㏖ phlorizin inhibited activity of enzyme to 48% and 45%, respectively. Its optimum wavelength was 690 ㎚ on the effect of K^+ ion influx, its optimum pH and temperature were found to be 7.2 and 55℃.
