[Metalloproteinases. Structure and function].

Matrix metalloproteinases (MMPs) belong to a large family of multidomain zinc endopeptidases. They are one of the most important proteolitic enzymes which digest components of the extracellular matrix and abundant macromolecules on cell surface and take part in many physiological processes, such as apoptosis or angiogenesis. MMPs are also engaged in the pathogenesis of many diseases such as arthritis and cancer. The development of effective inhibitors and discovery of their mechanisms of action can have significant influence on therapeutic strategy.
