Renin is an aspartyl protease which is highly homologous to the lysosomal aspartyl protease cathepsin D. During its biosynthesis, cathepsin D acquires phosphomannosyl residues that enable it to bind to the mannose 6-phosphate (Man-6-P) receptor and to be targeted to lysosomes. The phosphorylation of lysosomal enzymes by UDP-GlcNAc:lysosomal enzyme N-acetylglucosaminylphosphotransferase (phospho...
Specific interactions between parasites and extracellular matrix components are an important mechanism in the dissemination of Chagas' disease. Binding of the extracellular matrix proteins to Trypanosoma cruzi receptors has been described as a significant step in this phenomenon. In this study, a specific proteinase activity was identified in cell-free extracts of amastigote, trypomastigote and...
Candida albicans resides mainly as a harmless commensal in the gastrointestinal tract, vagina and some cutaneous areas of humans. However, in individuals who are immunocompromised or debilitated in some other way, C. albicans is responsible for superficialy-localized or systemic infections. Candida albicans produces a large family of secreted aspartyl proteinases (Saps) which are key virulence ...
PURPOSE The aspartyl (Asp) residues 58 and 151 in αA-crystallin, and Asp36 and Asp62 in αB-crystallin in human lenses are known to be highly isomerized with aging. We investigate structural environments of these isomerizable aspartyl residues in α-crystallins of human lenses. METHODS To perform limited proteolysis experiments of purified human αA- and αB-crystallins, endoproteinase Asp-N (EC ...
Streptomyces strain K1-02, which was identified as a strain of Streptomyces albidoflavus, secreted at least six extracellular proteases when it was cultured on feather meal-based medium. The major keratinolytic serine proteinase was purified to homogeneity by a two-step procedure. This enzyme had a molecular weight of 18,000 and was optimally active at pH values ranging from 6 to 9.5 and at tem...
Secreted proteins play a crucial role in intercellular communication during embryogenesis and in the adult. We recently described a novel method, designated as secretion cloning, that allows identifying extracellular proteins exclusively based on their ability to be secreted by transfected cells. In this paper, we present the results of a large-scale screening of more than 90,000 clones from th...
Introduction. Secreted metabolites with enzymatic or toxic properties are important for effecting of Candida spp pathogenicity. The most clinically significant species is C. albicans. However, invasive infections associated auris have a great significance.

Human endothelial cells treated with either interleukin-1 beta, tumor necrosis factor-alpha, or phorbol myristate acetate secreted a metalloproteinase that hydrolyzed and inactivated the two major serine proteinase inhibitors (Serpins) found in plasma, alpha 1-proteinase inhibitor and alpha 1-antichymotrypsin. Surprisingly, the responsible metalloproteinase was identified as human interstitial ...
