Rieske cluster oxidation rates during a single turnover depend upon the type of substrate present. (A) Optical change at 464 nm when reduced BZDO (60 µM) was mixed with an O2 saturated reaction buffer containing the indicated substrate (5 mM) at 4 °C in a stopped-flow spectrophotometer. (B) The resulting optical change at 464 nm with 4-fluorobenzoate and residuals from single, double, and triple exponential function fits.
