Phenol increases the decay rate of the tryptophanyl radical. The dependence of the observed rate on phenol concentration is well modeled by saturation kinetics. The determined reaction rate of the transient, krxn, with phenol and the substrate binding constant, Kd, are 20 ± 2 s−1 and 2.3 ± 0.5 mM, respectively.
