E301A | 8% FAD semiquinone at the equilibrium. Mutation does not change quinone substrate specificity but confers the mixed single- and two-electron mechanism of quinone reduction, whereas wild-type uses a single-electron pathway. Change can be explained by the relative increase in the rate of second electron transfer | Anabaena sp. |
