Metallome

In biochemistry, the metallome is the distribution of metalions in a cellular compartment. The term was coined in analogy with proteome, as metallomics is the study of metallome: the "comprehensive analysis of the entirety of metal and metalloid species within a cell or tissue type". Therefore, metallomics can be considered a branch of metabolomics, even though the metals are not typically considered as metabolites.

An alternative definition of "metallomes" as metalloproteins or any other metal-containing biomolecules, and "metallomics" is a study of such biomolecules.
