Metalloproteins/Metalloenzymes synthetic

In many biocatalytic systems, the metal plays an important role at the active site (more than 50% of all known enzymes need a metal ion to be active), and usually the reaction intermediates reside on the metal ion in the enzyme. Bioinorganic catalysis is defined as a branch of catalysis dealing with processes performed with the aid of metalloenzymes, modified enzymes, and synthetic metal-containing molecules resembling the active site of metalloproteins.
