Two Key Ferredoxins for Nitrogen Fixation Have Different Specificities and Biophysical Properties

Chemistry – A European Journal, EarlyView.
Two ferredoxins, FdC and FdN, are collectively essential for the process of nitrogen fixation by the iron nitrogenase in R. capsulatus. We explore the biophysical factors, through spectroscopic and structural characterizations, which determine ferredoxin functionality and pathway specificity. The structure of FdC (PDB: 9I2A) and model of FdN (AF‐D5ARY6)
