P.6 left column bottom paragraph: "The release of iron mediated by superoxide radical anion has been demonstrated for the enzymes containing [4Fe–4S] clusters, which contain two ferrous and two ferric ions. Superoxide oxidizes one ferrous ion into a ferric ion according to the reaction (primary source)
[2Fe(II)2Fe(III)−4S]2++O⋅−2+2H+→[Fe(II)3Fe(III)−4S]3++H2O2 (eq. 26) For which the rate constant is about 10^8–10^9 1/M/s." |
