The reduction of ferricytochrome c ( cyt cIII), as well as some iron ligand complexes and chemically modified derivatives of cyt cIII, by two molybdenum(V)-cysteine complexes has been investigated as a model for electron transfer in molybdenum enzymes. The reduction of cyt cIII by di-μ-oxo-bis [oxo(L-cysteinato)molybdate(V)] (I) is first order in cyt cIII and zero order in I over a wide range in concentration of I at neutral pH. The reduction of cyt cIII by μ-oxo-bisfoxodihydroxo(L-cysteinato) molybdate(V)] (II) is first order in both reactants and has a rate several orders of magnitude greater …
