Key Concepts

MoFe Protein

The MoFe protein, or dinitrogenase, is the catalytic component of the nitrogenase complex where substrate binding and reduction occurs. It contains important metal cofactors that facilitate the conversion of dinitrogen into ammonia, thus playing the central role in the nitrogen fixation process by accepting electrons delivered by the Fe protein and using them to break the strong nitrogen triple bond.

Fe Protein

The Fe protein, also known as dinitrogenase reductase, is a critical component of the nitrogenase complex responsible for transferring electrons to the catalytic component of the enzyme. It binds and hydrolyzes ATP to supply the energy necessary for electron transfer, which is essential for activating the catalytic process of reducing atmospheric nitrogen into a biologically usable form.
