Correction to Multistep, Eight-Electron Oxidation Catalyzed by the Cofactorless Oxidase, PqqC: Identification of Chemical Intermediates and Their Dependence on Molecular Oxygen Florence Bonnot, Anthony T. Iavarone, and Judith P. Klinman* Biochemistry 2013, 52 (27), 4667−4675. DOI: 10.1021/bi4003315 Page 4674. In the last paragraph of the Discussion, we have misstated the ratio of Kd values for the binding of PQQ and PQQH2 to PqqC as 25. This ratio was based on a previously published Kd(PQQ) value of 2 nM, whereas in the present work, we estimate Kd(PQQ) to be 5 nM. The latter value leads to a Kd(PQQH2)/Kd(PQQ) ratio of ∼10.
