Porphyromonas gingivalis is a major pathogen associated with chronic periodontitis. Major virulence factors of this organism are its cell-surface located cysteine proteinases known as gingipains that include the Arg-specific proteinases RgpA, RgpB and the Lys-specific proteinase Kgp. The gingipains have been demonstrated to be essential for the virulence of the organism in animal models of dise...
The protein crystals found in potato (Solanum tuberosum L.) tuber cells consist of a single 85-kD polypeptide. This polypeptide is an inhibitor of papain and other cysteine proteinases and is capable of binding several proteinase molecules simultaneously (P. Rodis, J.E. Hoff [1984] Plant Physiol 74: 907-911). We have characterized this unusual inhibitor in more detail. Titrations of papain acti...
Lysosomal enzymes are initially synthesized as precursor polypeptides which are proteolytically cleaved to generate mature forms of the enzymatically active protein. The identification of the proteinases involved in this process and their intracellular location will be important initial steps in determining the role of proteolysis in the function and targeting of lysosomal enzymes. Toward this ...
During pathologic vessel remodeling, vascular smooth muscle cells (VSMCs) embedded within the collagen-rich matrix of the artery wall mobilize uncharacterized proteolytic systems to infiltrate the subendothelial space and generate neointimal lesions. Although the VSMC-derived serine proteinases, plasminogen activator and plasminogen, the cysteine proteinases, cathepsins L, S, and K, and the mat...
The differentiation of F9 and PSA-1 embryonal carcinoma cells to embryoid bodies composed of a mixture of parietal and visceral endoderm was accompanied by changes in their secretion of metalloproteinases. Differentiation was induced by retinoic acid and dibutyryl cyclic AMP (for F9 cells) or by removing cells from a substrate of feeder cells to alter cell-cell interaction and adhesion (for PSA...
We produced a recombinant cysteine proteinase of Clonorchis sinensis and tested its value as an antigen for serologic diagnosis of C. sinensis infections. The predicted amino acid sequence of the cysteine proteinase of C. sinensis was 58, 48, and 40% identical to those of cathepsin L cysteine proteinases from Paragonimus westermani, Schistosoma japonicum, and Fasciola hepatica, respectively. We...
