in the detergent industry. In this study, the extracellular alkaline serine protease gene, aprE, from Bacillusclausii was amplified by PCR and further cloned and expressed in B. subtilis WB600 using the pWB980 expression vector. Protease activity of the recombinant B. subtilis WB600 harboring the plasmid pWB980/aprEreached up to 1020 U/ml, approximately 3-folds higher than the nativ...

conclusions the incidence of mbls producing p. aeruginosa in patients with cf was not low. the findings indicate that the identification of drug-resistance patterns in p. aeruginosa and the detection of mbl-producing isolates are important in the prevention and control of infections. background respiratory infections caused by pseudomonas aeruginosa play an important role in the pathogenesis of...

random peptide libraries (rpl) displayed on the surface of filamentous bacteriophages have been extensively used as a tool to map epitopes or to identify antigenic mimics (mimotpoes) of disease-specific monoclonal antibodies or polyclonal sera. these rpl are engineered by the insertion of degenerate oligonucleotides, encoding a specific number of random amino acids, in frame with a bacteriophag...

proteases are important enzymes that their role in various industries is undeniable. however, keeping enzymes stable during its activity in harsh conditions is so important. in this study, protease enzyme was immobilized on the porous silica particles and its stability in different temperatures and phs was evaluated. first silica particles were aminated by 3-aminopropyltriethoxysilane then the ...

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...

one of the important parts of innate immunity is complement system that occurs in three different ways; the classic, the alternative and the lectin pathway. the four pattern recognition molecules that have been identified till now are mannose binding lectin (mbl), a component of lectin pathway, and three ficolins (ficolin1,-2 and -3) which compound to the carbohydrates of the cell surface. mbl ...

Kinetics of bacterial growth and protease production were monitored on a novel isolated moderately halophilic bacterium, Salinivibrio sp. strain MS-7, and maximum growth and protease activity was achieved after 48 hours at 30°C and 180 rpm. To determine the effect of various carbon sources on protease production, glucose, lactose, sucrose and maltose were investigated and  maximum production of...

Cold agglutinin disease is a rare autoimmune hemolytic anemia characterized by hemolysis that caused activation of the classic complement pathway. Sutimlimab, humanized monoclonal antibody, selectively targets C1s protein, C1 complex serine protease responsible for activating this
