Quantitative reevaluation of the redox active sites of crystalline bovine heart cytochrome c oxidase.
Mochizuki M, Aoyama H, Shinzawa-Itoh K, Usui T, Tsukihara T, Yoshikawa S. Mochizuki M, et al. Among authors: yoshikawa s. J Biol Chem. 1999 Nov 19;274(47):33403-11. doi: 10.1074/jbc.274.47.33403. J Biol Chem. 1999. PMID: 10559221 Free article.
These results suggest that the 2 extra oxidation equivalents in the original oxidized form, compared with the O(2)-oxidized form, are due to a bound peroxide produced by O(2) and electrons from the internal donors, consistently with a peroxide at the O(2) reduction site in the cr …
