Roles of MoFe protein α-274-histidine, α-276-tyrosine and α-277-arginine residues in Azotobacter vinelandii nitrogenase catalysis
Previous studies revealed that α-275-Cys provides an essential ligand to one of the Fe atoms on the FeMo-cofactor, and its substitutions resulted in inactive nitrogenase. In order to study the structural-functional relationship of the protein environment in this region with respect to the FeMo-cofac...
