[Kinetics of light-induced redox changes of high-potential cytochrome in the chromatophores of purple sulfur bacteria Ectothiorhodospira shaposhnikovii].
Light-induced redox changes of high-potential cytochrome Ch (Em 7.0 = + 290 mV) have been studied. It was found that after switching off the actinic light there is a delay in the cytochrome dark reduction. The extent of the delay depends on the intensity of actinic light, being the more the higher the intensity. A simple kinetic model is proposed to explain both kinetics of redox changes of the cytochrome and dependence of the delay upon the intensity of actinic light.
