15.15Explain how the lack of all reflections in the diffraction data analysis changes the calculated
electron density.
15.16 What are the possible advantages for the unusual homocitrate ligand of nitrogenase?
15.17 How do the different docking conformations facilitate the enzymatic function of
nitrogenase?
15.18 Suppose that an EXAFS experiment shows the presence of one peak at 2.3 Å for a
metalloprotein with a metal cluster. What is the interpretation of the peak?
