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

The purpose of this study is to improve the thermo-stabilty of alkaline protease produced by Bacillus sp. using rice bran during solid state fermentation. After partial purification of alkaline protease, various parameters namely effect of temperature and metal ions on enzyme activity was investigated. The suitable temperature for alkaline protease activity was observed at 50°C. Among various m...

Netherton syndrome is a congenital ichthyosis associated with erythroderma, hair shaft defects, and atopic features. The mutations of the secretory serine protease inhibitor Kazal-type 5 gene have been identified in Netherton syndrome patients; however, the actual physiologic substrates of the serine protease inhibitor Kazal-type 5 proprotein are unknown, and how the genetic defects cause chara...

Background: To investigate the levels and clinical significance of serum homocysteine (Hcy), high-density lipoprotein cholesterol (HDL-C), visceral adipose tissue-derived serine protease inhibitor (vaspin), fat-specific adipokine (visfatin) in elderly patients with different types coronary heart disease (CHD).

Proteases are the most important group of the enzymes produced commercially and industrial purpose[1,2]. They have extensive applications in a range of industrial products and processes including detergents, food, pharmaceuticals and leather[3,4]. They are classified into various groups such as alkaline protease, serine protease, cystein protease, aspartic protease and metallo protease[5]. Prot...

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...

Serine protease cascades boost immune responses while maintaining homeostasis. These crucial actions are intricately regulated by cognate serine protease inhibitors. However, the mechanism underlying such a dynamic immunomodulation during acute phase infection remains obscure, particularly where the pathogen's serine protease adds a new challenge to the host. Here, we found that infection of ho...

Novel keratin-degrading bacteria were isolated from sand soil samples collected from Minia Governorate, Egypt. In this study, the isolates were identified as Bacillus amyloliquefaciens MA20 and Bacillus subtilis MA21 based on morphological and biochemical characteristics as well as 16S rRNA gene sequencing. B. amyloliquefaciens MA20 and B. subtilis MA21 produced alkaline keratinolytic serine pr...

Proteases are the most studied microbial enzymes at commercial, industrial, pharmaceutical analytical, diagnostic, effluent abatement and other sectors. An effective proteolytic enzyme producing microbial strain has been isolated from marine soil under banana tree and evaluated its extracellular protease production properties with respect to different fermentative physiological parameters. The ...
