this quinone derivative is used in the study because the natural C45-plastoquinone is not available commercially
plastoquinone
quinone
-
since phytoene desaturation responds to the redox state of quinones, which is adjusted by the respiratory redox pathway, the two reactions must be regarded as being mechanistically linked. Using redox titrations, it is shown that the optimal activity lies in the range of the midpoint potential of the plastoquinone/plastohydroquinone redox couple
