A simplified reaction scheme for the conversion of AFB1 to AFQ1 when exposed to a laccase. It is hypothesized that 2 AFB1 molecules each contribute 2 electrons to the reaction, with 3 electrons being stored in the T3 site and 1 in the T1 center. Once the fourth electron is withdrawn from the AFB1, the reaction of O2 to H2O is immediately catalyzed.
