Bacterial collagenases – A review

Critical Reviews in Microbiology, 2014
Bacterial collagenases are metalloproteinases involved in the degradation of the extracellular matrices of animal cells, due to their ability to digest native collagen. These enzymes are important virulence factors in a variety of pathogenic bacteria. Nonetheless, there is a lack of scientific consensus for a proper and well-defined classification of ...

Chemonucleolysis (Discolysis) with Collagenase

Spine, 1986
Fifty-four patients with proven lumbar disc displacement were treated by intradiscal injection of collagenase (Nucleolysin) between April 1981 and January 1984. Follow-up by history and physical examination, phone survey, and/or mail survey shows 72% success rate (excellent, good, and fair) and 28% poor or unsuccessful results.

The preparation of purified collagenase

Archives of Biochemistry and Biophysics, 1963
Abstract Two methods are described for the purification of Clostridium histolyticum collagenase. One method involves gel filtration on columns of Sephadex G-200, the other, ion-exchange chromatography on DEAE Sephadex A-50. In both cases, calcium-containing buffers were found necessary for good recoveries of enzyme.

The Collagenase of Carrageenin Granuloma

Connective Tissue Research, 1974
A study has been made of the collagenase present in carrageenin granulomas. The enzyme revealed the following characteristics: (1) it is not present in crude tissue extracts of resorbing carrageenin granulomas but may be revealed by the tissue explant technique; (2) culture medium harvested during the first 5 days of tissue explant usually shows no ...

Regulation of the Mammalian Collagenases

Collagen and Related Research, 1984
Gross and Lapiere (1962) discovered vertebrate collagenase in cultures of resorbing tadpole tissue. By ultrastructural techniques it was shown that collagenase cleaves each triple helical collagen molecule at only one site approximately three-quarters from the amino terminus (Gross and Nagai, 1965).

Collagenase in Cranial Morphogenesis

Cells Tissues Organs, 2005
Collagen is the most abundant extracellular matrix protein in connective tissues of higher animals. The growth of connective tissues is intimately linked to the ability to model and remodel the collagen-rich matrices of the organism at critical points during development and growth to allow expansion and adaptation of tissue interfaces.

Collagenase in synovial fluid

Scandinavian Journal of Rheumatology, 1978
Free collagenase activity was demonstrated in all 13 normal, 5 osteoarthrotic and 54 rheumatoid synovial fluids studied. Osteoarthrotic, normal, and rheumatoid fluids showed a free collagenase content increasing in that order. However, the total activities after trypsin activation did not differ significantly. The concentrations of alpha1-at and alpha2-
