"...the enzyme [was] reconstituted in proteoliposomes." (see Text) "Translocation of electrical charge during the reaction was determined by time resolved electrometry" (see Legend of Fig. 8). Ubiquinol oxidase activity was measured at 25 °C using a Clark-type oxygen electrode. Ubiquinone content and steady state reduction level of heme b were measured spectrophotometrically (Table 2).
