Respiration-induced organic radicals in V. cholerae membranes in the presence and absence of a functional Na+-NQR. Membranes from the wild-type V. cholerae strain (black trace) and from the nqrC insertion mutant (gray trace) were mixed with 7.3 mM Na2-NADH (top) or 36.4 mM Na2-succinate (bottom) prior to freezing. EPR conditions: microwave frequency, 9.652 GHz; modulation amplitude, 0.5 mT; microwave power, 4 μW; temperature, 70 K.
