Metalloproteinases (or metalloproteases) constitute a family of enzymes from the group of proteinases.
Metalloproteinases bind a metal ion such as Zn2+ or Ca2+ in their active site.
Important metalloproteinases are the bacterial enzyme thermolysin (which is a metalloendopeptidase), the digestive enzymes carboxypeptidase A or B (which are metallocarboxypeptidases), and the matrix metalloproteinases (MMP, also metalloendopeptidases).
