The aim of this study was to clarify the pathway of electron transfer between the inner membrane components and the periplasmic chlorate reductase. Several soluble c-type cytochromes were found in the periplasm. The optical difference spectrum of dithionite-reduced periplasmic extract shows that at least one of these components is capable of acting as an electron donor to the enzyme chlorate reductase. The cytochromes were partially separated, and the fractions were analyzed by UV/visible… CONTINUE READING
