Metalloprotein

A metalloprotein is a protein with a metal ion cofactor. Many proteins are members of this category, so the number of them is large.

It is estimated that about half of all proteins contain a metal.Thomson A.J. & Gray H.B. 1998. "Bio-inorganic chemistry". Current Opinion in Chemical Biology. 2, 155-158.   In another estimate, about one-quarter to one-third of all proteins need metals to carry out their functions. Thus, metalloproteins have many different functions in cells, such as enzymes, transport and storage proteins, and signal transduction proteins.
