Description: 

 

These slides describe the recent literature on the structure of the iron sulfur cluster of nitrogenase active site, FeMo-co.  Included are: a comparison of industrial vs. biological ammonia production, several crystal structures from the literature including the unknown until recently hypervalent carbon atom in the center, and a brief mention of the troubling sterics of the active site as crystallized.

Learning Goals: 

 

After discussion of these slides students will be familiar with...

  • The differences between industrial and biological ammonia production
  • The history of elucidation of the structure and active site of nitrogenase
  • The idea that a literature report can be groundbreaking yet still have many unanswered questions remaining
  • If the structural evidence suggests it, carbon might juts be able to form 6 "bonds"!
