Abstract

Metallo-enzymes and metallo-proteins are a combination of a metal ion or several metal ions in which the metal ion is strongly held in a protein. Hence, before describing their properties and functions, it is necessary to appreciate which metal ions bind strongly to proteins and exchange slowly. The biological significance of metallo-enzymes is that they are essential catalysts, especially for the metabolism of small molecules such as H2, CH4, CO, N2, and O2, as well as for long-range electron transfer. The control of uptake and the synthesis of their proteins rest with feedback in a series of metallo-proteins.
