Differential susceptibility of type X collagen to cleavage by two mammalian interstitial collagenases and 72-kDa type IV collagenase.
We have studied the degradation of type X collagen by human skin fibroblast and rat uterus interstitial collagenases and human 72-kDa type IV collagenase. The interstitial collagenases attacked the native type X helix at two loci, cleaving residues Gly92-Leu93 and Gly420-Ile421, both scissions involving Gly-X bonds of Gly-X-Y-Z-A sequences. However, the human and rat interstitial enzymes displa...
متن کاملMMP 2 ( matrix metallopeptidase 2 ( gelatinase A , 72 kDa gelatinase , 72 kDa type IV collagenase ) .
Description MMP2 is a Zn dependent endopeptidase, synthesized and secreted in zymogen form. The nascent form of the protein shows an N-terminal signal sequence ('pre' domain) that directs the protein to the endoplasmic reticulum. The pre domain is followed by a propeptide'pro' domain that maintains enzyme-latency until cleaved or disrupted, and a catalytic domain that contains the conserved zin...
متن کاملIntracellular activation of gelatinase A (72-kDa type IV collagenase) by normal fibroblasts.
Normal fibroblasts cultured as monolayers secrete matrix metalloproteinases (MMP), including gelatinase A (72-kDa type IV collagenase) as inactive zymogens. Previously we found that normal fibroblasts cultured in a type I collagen lattice (dermal equivalent) secrete active gelatinase A. Here we show that the activation of progelatinase A occurs within the cell and that the activator copurifies ...
متن کاملGelatinase Expression of Interstitial Collagenase, Stromelysin, and 72-kDa Tumor Cell-derived Collagenase-stimulatory Factor Increases
The tumor cell-derived collagenase-stimulatory factor (TCSF) was pre viously purified from human lung carcinoma cells (S. M. Ellis, K. Nabeshima, and C. Biswas, Cancer Res., 49: 3385-3391, 1989). This protein is present on the surface of several types of human tumor cells in vitro and in vivo and stimulates production of interstitial collagenase in human fibroblasts. In this study it is shown t...
متن کاملEvidence of in vitro differential secretion of 72 and 92 kDa type IV collagenases after selective exposure to lipopolysaccharide in human fetal membranes.
Premature rupture of chorioamniotic membranes complicated with intrauterine infection has been associated to degradation of extracellular matrix (ECM), which could explain local morphological changes. We used a culture system in which the chorioamniotic membranes form two independent chambers, allowing for the selective stimulation of either the amnion (AMN) and/or the choriodecidua (CHD) regio...
