Hepatitis C virus (HCV) infection is a global health burden with over 170 million people infected worldwide. In a significant portion of patients chronic hepatitis C infection leads to serious liver diseases, including fibrosis, cirrhosis, and hepatocellular carcinoma. The HCV NS3 protein is essential for viral polyprotein processing and RNA replication and hence viral replication. It is compos...
PLANT-PIs is a database developed to facilitate retrieval of information on plant protease inhibitors (PIs) and related genes. For each PI, links to sequence databases are reported together with a summary of the functional properties of the molecule (and its mutants) as deduced from literature. PLANT-PIs contains information for 351 plant PIs, plus several isoinhibitors. The database is accessi...
The correct balance between proteases and their natural protein inhibitors is of great importance in living systems. Protease inhibitors usually comprise small folds that are crosslinked by a high number of disulfide bonds, making them perfect models for the study of oxidative folding. To date, the oxidative folding of numerous protease inhibitors has been analyzed, revealing a great diversity ...
The isolation of therapeutic and functional protease inhibitors in vitro via combinatorial chemistry and phage display technology has been described previously. Here we report the construction of a combinatorial mouse-human chimeric antibody fragment (Fab) antibody library targeted against the protease of the tropical pathogen, Burkholderia pseudomallei. The resulting library was biopanned agai...
We describe a genetic system that allows in vivo screening or selection of site-specific proteases and of their cognate-specific inhibitors in Escherichia coli. This genetic test is based on the specific proteolysis of a signaling enzyme, the adenylate cyclase (AC) of Bordetella pertussis. As a model system we used the human immunodeficiency virus (HIV) protease. When an HIV protease processing...
Serine protease performs normal biological functions in cell. Serine protease are involves in coagulation, inflammation and immunity. Wide variety organisms produce serine proteases including virus, bacteria, animals and plants. Serine proteases are mono-meric enzymes. Serine protease are produced as inactive enzymes called zymogen and transported to other organs where they needed, which are th...
Proteolytic activation of Sendai virus in the lungs of mice is necessary to cause pneumopathogenicity. Using Sendai virus-infected lung block cultures, protease inhibitors were tested for their antiviral effect by examining inhibition of proteolytic activation. Among the inhibitors tested, a serine protease, aprotinin, was shown to be most effective. In vivo protection experiments demonstrated ...
Protease inhibitors are very effective in their ability to suppress carciiKiurncsis in many different in v/ro and in vitro assay systems. One particularly effective protease inhibitor, the soybean-derived BowmanKirk inhibitor, has been extensively studied in our laboratory. Our results have indicated that Bowman-Birk inhibitor suppresses carcinogenesis I ) induced by several different types of ...
UNLABELLED Resistance to various human immunodeficiency virus type 1 (HIV-1) protease inhibitors (PIs) challenges the effectiveness of therapies in treating HIV-1-infected individuals and AIDS patients. The virus accumulates mutations within the protease (PR) that render the PIs less potent. Occasionally, Gag sequences also coevolve with mutations at PR cleavage sites contributing to drug resis...
