  1. 1. Haematopoietic Serine Proteases : A Cleavage Specificity Analysis

    Author : Michael Thorpe; Lars Hellman; Urban Gullberg; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Mast cell; cleavage specificity; phage display; chymase; serine protease; granzyme; fish protease;

    Abstract : Mast cells are innate immune cells, historically involved in allergy responses involving IgE. Through this, they have earned a reputation as a fairly detrimental cell type. Their beneficial roles remain somewhat enigmatic although they clearly have the ability to modulate the immune system. READ MORE

  2. 2. A thermostable alkaline protease from a new alkaliphilic Nesterenkonia sp

    Author : Shahrzad Bakhtiar; Bioteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; substrate specificity; crystallization; Biotechnology; Bioteknik; DNA-DNA hybridisation; 16S rDNA analysis; phenotypic characterisation; circular dichroism; differential scanning calorimetry; Nesterenkonia abyssinica; stability; calcium-independent; alkaline protease; alkaliphilic;

    Abstract : This thesis concerns a novel alkaline protease produced by an extremophilic microbial specie, designated as AL20, isolated from a feather sample collected at the shore of the alkaline soda lake Abjata in the Ethiopian Rift Valley. The isolate is a heterotrophic, alkaliphilic, halotolerant gram-positive, strictly aerobic, non-motile, non-spore forming bacterium. READ MORE

  3. 3. Cutting Edge – Cleavage Specificity and Biochemical Characterization of Mast Cell Serine Proteases

    Author : Ulrika Karlson; Lars Hellman; Urban Gullberg; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biology; mast cell; serine protease; tryptase; chymase; substrate specificity; phage display; Biologi; Biology; Biologi; Molecular Immunology; molekylär immunologi;

    Abstract : It is well established that mast cells (MC) are key players in airway pathologies such as allergic asthma, but they are also known to contribute to host defense and tissue remodeling. MC serine proteases are the major protein components of mast cell granules and accordingly, are most likely involved in many aspects of MC function. READ MORE

  4. 4. Cleavage Specificity of Mast Cell Chymases

    Author : Mattias K. Andersson; Lars Hellman; Gunnar Pejler; Per Venge; Uppsala universitet; []
    Keywords : Biology; Immunology; Mast cell; Serine protease; Chymase; Cleavage specificity; Phage display; Biologi;

    Abstract : Mast cells (MC) are potent inflammatory cells that are known primarily for their prominent role in IgE mediated allergies. However, they also provide beneficial functions to the host, e.g. in bacterial and parasitic defence. READ MORE

  5. 5. The cell biology and catalytic properties of the nutrient-induced signaling endoprotease Ssy5

    Author : António Martins; Per O. Ljungdahl; Bruno André; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Nutrient sensing; signal transduction; regulated proteolysis; endoprotease; serine protease; substrate specificity; subcellular fractionation; Saccharomyces cerevisiae; Cell Biology; cellbiologi;

    Abstract : Cells continuously sense and respond to changes in the presence, quality and quantity of external and internal nutrients. Specific signaling proteases have been identified based on their roles in processing or destruction of distinct sets of downstream effector proteins in response to environmental cues. READ MORE
