[Model molybdenum-sulfur and molybdenum-iron-sulfur protein complexes].
A procedure was developed for synthesizing complexes of polynuclear molybdenum sulfide and iron-molybdenum sulfide on the basis of human serum albumin. EPR showed that molybdenum and iron atoms formed clusters in the synthesized complexes. The catalytic activity of the complexes, as determined through reaction of acetylene reduction by sodium borohydride, was significantly higher than that for previously described nonbiological systems, but lower than the characteristic values of FeMo-cofactor of nitrogenase.
