FeSII β-chain are indicated by an (’). Nitrogenase residues marked with an asterisk (*) belong to the Fe-protein and those without are from MoFe-protein. Polar interactions were classified in salt bridges and hydrogen bonds. Atoms participating on these contacts were separated in backbone or side-chain atoms.
