Design and Synthesis of Redox or Catalytically Active Artificial Metalloproteins Containing Non-Native Inorganic and Organometallic Complexes
207 p. Thesis (Ph.D.)--University of Illinois at Urbana-Champaign, 2006. The design and synthesis of new proteins with novel binding and catalytic properties has been an active area of study for the past three decades. In an effort to expand the redox and catalytic activity of native proteins and to...

In an effort to expand the redox and catalytic activity of native proteins and to transform synthetic inorganic and organometallic complexes into environmentally benign asymmetric catalysts, we have covalently attached metal complexes, such as ferrocene and manganese salen (Mn(Salen)) to the active sites of cytochrome c peroxidase (CcP) and sperm whale myoglobin (Mb) using cysteine residues.
