==Overview==

The x-ray crystal structure of NifV(-) Klebsiella pneumoniae nitrogenase, MoFe protein (NifV(-) Kp1) has been determined and refined to a resolution, of 1.9 A. This is the first structure for a nitrogenase MoFe protein with, an altered cofactor. Moreover, it is the first direct evidence that the, organic acid citrate is not just present, but replaces homocitrate as a, ligand to the molybdenum atom of the iron molybdenum cofactor (FeMoco)., Subsequent refinement of the structure revealed that the citrate was, present at reduced occupancy.
