“Metalloproteomics” is a relatively new and not that widely known term. Today (20 October 2009), PubMed search produces only 13 hits. (The search for “metallomics” gives only twice as many hits.) The earliest use of the term is by Alfredo Sanz-Medel and by Scott et al. — incidentally, both papers were published online 23 December 2004.

Metalloproteomics by Eugene Permyakov (Wiley-Interscience, 2009) gives us a definition of the term:
Metalloproteomics is a proteomics of metal-binding proteins.
That’s easy, right? But wait. Check out the table of contents. It looks to me like another bioinorganic chemistry book, and a rather pricey one. It mostly deals with metalloproteins, but there are also Chapter 15, Interactions of metal cations with nucleic acids, and Chapter 16, “Nonphysiologic” metals. Nothing here is specifically proteomic or metallomic. I suppose that Chapter 3, Experimental methods used for studies of the binding of metal cations could be of some relevance to metalloproteomics. Then again, maybe not: how come that mass spectrometry, the most obvious proteomics technique, is not mentioned at all? And why metal cations only? Some metalloproteins contain vanadate. Maybe I am jumping to conclusions here (without even reading the book!), but this title is simply misleading.
