It is well-known that molecular oxygen inhibits nitrogenase.  I 
assume that this may have something to do with causing oxidation of 
the metals (Mo and Fe) that are in the enzyme.  A student asked if 
the inhibition was reversible or irreversible.  No source that I have 
consulted answers this question, although one used the word 
"denaturation" in reference to the oxygen effect on the protein.

Any thoughts?
