a Comparison of the partial Mo-lactate-triazole in 1 (front, opaque) with Mo-homocitrate-histidine coordinated unit in Mo-nitrogenase (behind, at a transparency of 30%)10. Color: molybdenum, violet; oxygen, red; nitrogen, blue; carbon, gray. b Double chiral centers of FeMo-co in Mo-nitrogenase. c Suggested structure for the extracted FeMo-co with N-methylformamide (NMF), where amino acids in green boxes of b have been replaced by NMF in red boxes of c.
