Abstract: Nitrogenases catalyse the 6-electron reduction of dinitrogen to ammonia, passing through a series of redox and protonation levels during catalytic substrate reduction. The molybdenum-iron nitrogenase is the most well-studied, but redox potentials associated with proton-coupled… read more here.

DOI: 10.7554/elife.79311
Abstract: The nitrogenase Fe protein mediates ATP-dependent electron transfer to the nitrogenase MoFe protein during nitrogen fixation, in addition to catalyzing MoFe protein independent substrate (CO2) reduction and facilitating MoFe protein metallocluster biosynthesis. The precise role(s)… read more here.
