... inability of PTOX to use ubiquinone is an artefact of this assay (which relies on the ability of the membranes to reduce quinones). Therefore, we propose that the preference of PTOX for plastoquinol ... due to a strong preference of PTOX for plastoquinol over duroquinol, or to a lower concentration of duroquinol in the NADH-based assay. Fig. 6. Chemical structures of pla...
