'''Metalloproteases''' are [http://en.wikipedia.org/wiki/Proteases proteases] where the water molecule that is used for hydrolysis is complexed to a metal ion in the catalytic center of the enzyme. The metal ion is itself hold in position by several amino acid residues. The metalloproteases are one of seven superclans of the proteases in the UniProt/MEROPS classification.

== Classification ==
<applet load='1xyz' />
A first raw classification is that into exo- and endopeptidases, according to whether the protein is cleaved at the end or not. The most advanced classification is that edited by UniProt and available at the MEROPS database (see link below). It lists 54 families of closely related metalloproteases that are grouped into 15 clans. We have chosen six examples from different clans that can be viewed by clicking on the green links, each with an additional center scene:

*neutral zinc metallopeptidases, example thermolysin from ''Bac. stearothermophilus'' ([[2a7g]]). Matrix metallopeptidases and a lot of well-known other proteases belong to this big clan.
*carboxypeptidases, example carboxypeptidase A (''Bos taurus'', [[5cpa]])
*insulinases, example pitrilysin (''E. coli'', [[1q2l]])
*cytosol-aminopeptidases, example leucyl aminopeptidase (''Bos taurus'', [[1lam]])
*methionin-aminopeptidases, example human methionine aminopeptidase ([[2b3k]])
*renal dipeptidases, example human renal dipeptidase ([[1itq]])
