background: proteolytic enzymes have an important role in variety of physiological and pathological functions. they have been used in therapeutic and pharmaceutical applications. characterizations of extracellular proteases from various strains of s. marcescens indicate that most strains produce a very similar major metalloprotease. this metalloprotease (serrapeptidase, serrapeptase) is an impo...

Vibrio vulnificus biotype 1, a causative agent of fatal septicemia or wound infection in humans, is known to produce a toxic metalloprotease as an important virulence determinant. V. vulnificus biotype 2 (serovar E), a primary eel pathogen, was found to elaborate an extracellular metalloprotease that was indistinguishable from that of biotype 1. The potential of V. vulnificus biotype 1 for prod...
ADAM metalloprotease-disintegrins share a common modular structure of functional domains for proteolytic, cell adhesion, and signaling interactions. The metalloprotease domain of oughly half of the known ADAMs contain an intact consensus metzincin catalytic site, and they are thus thought to function as active metalloproteases. The types of interactions mediated by ADAMs are expressly conspicu...
Formation of thrombin during incubation of purified bovine prothrombin with purified staphylococcal metalloprotease has been investigated. Thrombin activity was estimated by examination of clotting time and by digestion of a synthetic substrate, Chromozym TH. The metalloprotease caused direct activation of prothrombin which was inhibited by the addition of ethylenediaminetetraacetic acid. Metal...
actinomycetes are an uncommon agent of human infections and its pathogenic factors are not known. the present study reports a rare case isolation of an actinomycete from a woman pleural fluid; the strain was identified by 16s rrna gene sequence analysis. this strain was tested to produce an extracellular protease that hydrolysis gelatin, casein and hemoglobin on agar mediums. the purification o...
A rapid and robust recruitment of circulating neutrophils at sites of infection is critical for preventing bacterial spread. The efficiency of this process, however, is greatly diminished during sepsis, a severe systemic inflammatory response to infection. The proteolytic activity of a disintegrin and metalloprotease-17 is induced in the cell membrane of leukocytes upon their activation, result...
Proteolytic release from the cell surface is an essential activation event for many growth factors and cytokines. TNF-α converting enzyme (TACE) is a membrane-bound metalloprotease responsible for solubilizing many pathologically significant membrane substrates and is an attractive therapeutic target for the treatment of cancer and arthritis. Prior attempts to antagonize cell-surface TACE activ...
The treatment of HL-60 promyelocytic leukemia cells with phorbol esters (12-O-tetradecanoylphorbol-13-acetate) results in the appearance of cell substrate adhesion and the release of a Mr 94,000 gelatin-degrading metalloprotease. The appearance of the metalloprotease in the culture medium directly correlates with the timing and extent of cell substrate adhesion over a 24-h period. Anti-Mr 94,00...
