Dinitrogen Reduction: Interfacing the Enzyme Nitrogenase with Electrodes.

Potential for nitrogenase: Milton, Minteer, and co-workers report the first evidence for the bioelectrochemical reduction of N2 to ammonia by nitrogenase. This complex enzyme could be wired to an electrode by using the soluble mediator methyl viologen; this very simple approach makes it possible to develop a variety of biotechnological devices.
