The presence of a pterin-dithiolene (MPT-based) ligand at Mo is the unifying feature of the various molybdenum cofactors (Moco s) and enzymes. " The chemical nature of the pterin-dithiolene ligand was defined by degradative and spectroscopic studies performed by Rajagopalan, Johnson, and coworkers. They proposed the bicyclic structure (4) and... [Pg.2781]

Molybdenum extended X-ray absorption fine structure (EXAFS) studies yielded the first structural insight into a metallocenter of nitrogenase. The results of these initial analyses delivered compositional and metrical data on the molybdenum environment and led to the identification of the FeMo-cofactor as a Mo-Fe-S cluster. One proposal for an EXAFS-consis-tent local molybdenum environment was a MoFe3S4 eubane model derived from the established Fe4S4 structure. Independent synthetic efforts from Holm and Garner quickly yielded species possessing this motif in the form... [Pg.149]
