Collectively they are capable of degrading all kinds of molecules. They are known to be involved in in/activation. MMPs are also thought to play a major role on cell behaviors such as . They are distinguished from other endopeptidases by their s were described by Jermome Gross and Charles Lapiere (1962) who observed triple helix degradation) during tadpole tail metamorphosis (PMID he enzyme was named interstitial collagenase (MMP purified from human skin (1968) (PMID 4967132), and was recognized to be ption of the "cysteine switch" was described in 1990 Structure
- peptide domain is part of “cysteine switch” this keeping the enzyme in an inactive form. In the majority of prohormone convertase cleavage site (Furin - like) as part of this domain which when cleaved The catalytic domain
structures of several MMP catalytic domains have shown that this domain is an oblate sphere measuring 35 x 30 x 30 ed sequence HExxHxxGxxH. Hence, this sequence is a zinc zinc- binding motif in the catalytic domain (PMID 12486137).
The hinge region
The catalytic domain is connected to the C long, and has no determinable structure.
- terminal domain has structural similari interaction with TIMP’s. The haemopexin Classification

The MMPs can be subdivided in different ways. Use of MMP - 19; MMPs 11, 14, 15, 16 and 17; MMP tic domains in isolation suggests that the catalytic domains evolved further once the major groups had differentiated, as is also indicated by the . The most commonly used groupings (by researchers in MMP biology) are based partly on historical assessment of the substrate specificity of the MMP and partly on the of the MMP. These groups are the collagenases, the gelatinases, the stromelysins, - MMPs). It is becoming increasingly clear that these divisions are somewhat artificial as there are a number of MMPs that do not fit into any Archetypal MMPs
These MMPs are capable of degrading triple capable of degrading them. Traditionally, the collagenases are: MMP - 18 (Collagenase 4, xcol4, xenopus collagenase. - MMP) has also been shown to cleave fibrillar The stromelysins
These enzymes display a broad ability to cleave . The three canonical members of this group are: therefore usually associated to convertase Other MMPs
- 1, occasionally referred to as stromelysin The matrilysins
distinguished by the presence of an additional domain inserted into the catalytic domain. This - binding region is positioned immediately before the does not disrupt the structure of the catalytic domain. The two Convertase

The MMPs are inhibited by specific endogenous tissue inhibitor of metalloproteinases (TIMPs), all MMPs are inhibited by TIMPs once they are activated but the gelatinases (MMP 9) can form complexes with TIMPs when the enzymes are in the latent form. The complex of site tightly. Common chelating groups include . Hydroxymates are particularly potent inhibitors of MMPs and other zinc dependent enzymes, due to their bidentate these inhibitors are usually designed to interact with various binding pockets on the MMP of interest, making the inhibitor more or less specific for given MMPs.
, at subantimicrobial doses, inhibits MMP activity, and has been used in various is widely available clinically. It is sold under the trade name A number of rationally designed MMP inhibitors have shown some promise in the treatment of MMPs are suspected to be involved in (see above). However, most of these, - 2516), a broad spectrum MMP inhibitor, and MMP - 1 selective inhibitor, have performed poorly in drugs has been largely due to toxicity (particularly musculo - skeletal toxicity in the case of broad spectrum inhibitors) and failure to show expected results (in the case of trocade, promising results in rabbit arthritis models were not replicat largely disappointing clinical results of MMP inhibitors are External links
