Matrix metalloproteinases (MMPs)
| MMP designation* | Common name (other or previous names) |
| MMP-1 | Collagenase-1 (fibroblast collagenase, interstitial |
| collagenase) | |
| MMP-2 | Gelatinase-A (72 kDa gelatinase, 72 kDa type IV |
| collagenase) | |
| MMP-3 | Stromelysin-1 (transin-1) |
| MMP-7 | Matrilysin (PUMP) |
| MMP-8 | Collagenase-2 (neutrophil collagenase) |
| MMP-9 | Gelatinase-B (92 kDa gelatinase, 92 kDa type IV |
| collagenase) | |
| MMP-10 | Stromelysin-2 (transin-2) |
| MMP-11 | Stromelysin-3 |
| MMP-12 | Macrophage metalloelastase |
| MMP-13 | Collagenase-3 (rat collagenase) |
| MMP-14 | MT1-MMP (membrane-type MMP) |
| MMP-15 | MT2-MMP |
| MMP-16 | MT3-MMP |
| MMP-17 | MT4-MMP |
| MMP-18 | Collagenase-4† |
| MMP-19 | |
| MMP-20 | Enamelysin |
| MMP-21 | |
| MMP-22 | |
| MMP-23 | CA-MMP |
| MMP-24 | MT5-MMP |
| MMP-25 | Leukolysin (MT6-MMP) |
| MMP-26 | Endometase (matrilysin-2) |
*There is no MMP-4, MMP-5, or MMP-6. After matrilysin was discovered and designated as MMP-7, MMP-4 to MMP-6 were determined to be either MMP-2 or MMP-3. †Collagenase-4 was isolated from Xenopus. A mammalian homolog has not been found.
