the cyt bc1 complex catalyzes the antimycin-sensitive electron transfer reaction from lipophilic substrate ubiquinol to cytochrome c coupled with proton translocation across the membrane. As a result, for every quinol molecule oxidized, four protons are deposited to the positive side of the membrane and two molecules of cytochrome c are reduced. Key step in the Q-cycle mechanism is the separation of the two electrons of the substrate quinol at the QP site

ubiquinol + 2 ferricytochrome c
ubiquinone + 2 ferrocytochrome c + 2 H+
-
under physiological conditions, the dimeric cytochrome bc1 complex is suggested to be continually primed by prompt oxidation of membrane ubiquinol via center N yielding a bound semiquinone in this center and a reduced, high-potential heme b in the other monomer of the enzyme. Then the oxidation of each ubiquinol molecule in center P is followed by ubiquinol formation in center N, proton translocation and generation of membrane voltage

-
the cyt bc1 complex catalyzes the antimycin-sensitive electron transfer reaction from lipophilic substrate ubiquinol to cytochrome c coupled with proton translocation across the membrane. As a result, for every quinol molecule oxidized, four protons are deposited to the positive side of the membrane and two molecules of cytochrome c are reduced

reaction mechanism of superoxide generation by bc1, overview. Maximum superoxide anions generation activity is observed when the complex is inhibited by antimycin A or inactivated by heat treatment or proteinase K digestion. The protein subunits, at least those surrounding the QP pocket, may play a role either in preventing the release of superoxide. from its production site to aqueous environments or in preventing O2 from getting access to the hydrophobic QP pocket and might not directly participate in superoxide production
