Synergic binding of carbon monoxide and cyanide to the FeMo cofactor of nitrogenase: relic chemistry of an ancient enzyme?
The first electrochemical and infra-red data on the binding of cyanide to the isolated iron-molybdenum cofactor of nitrogenase, FeMoco, is described. It is shown that cyanide stabilises a hitherto unrecognised, low-spin, EPR-active (S= 1/2), superoxidised form of FeMoco, and we provide the first evi...
