  1. 1. Folding and Structure of Azurin - The Influence of a Metal

    Författare :Johan Leckner; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; azurin; metal cofactor; disulfide bond; protein folding; solution structure; protein stability; paramagnetic NMR;

    Sammanfattning : The structural role of the metal in the protein azurin from Pseudomonas aeruginosa has been a long standing question. Azurin belongs to the cupredoxin family and is a 128 residue beta-barrel protein of greek-key topology. LÄS MER

  2. 2. Membrane-bound thiol-disulfide oxidoreductases in Bacillus subtilis

    Författare :Lydur Erlendsson; Institutionen för experimentell medicinsk vetenskap; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; virologi; mykologi; Mikrobiologi; mycology; virology; bacteriology; Microbiology; sporulation; cytochrome c; thiol-disulfide oxidoreductases; Bacillus subtilis; membrane proteins; bakteriologi;

    Sammanfattning : Disulfide bonds in proteins are found between cysteine residues and are usually important for either function or stability of proteins. Thiol-disulfide oxidoreductases catalyse the formation or breakage of disulfide bonds in proteins. LÄS MER

  3. 3. Studies on Thiol-Disulfide Oxidoreductases in Bacillus subtilis

    Författare :Mirja Carlsson Möller; Molekylär cellbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; virology; mycology; Mikrobiologi; bakteriologi; virologi; mykologi; Microbiology; bacteriology; bacterial sporulation; endospore; thioredoxin; Thiol-disulfide oxidoreductase;

    Sammanfattning : Bacillus subtilis is a model organism for endospore-forming gram-positive bacteria. Endospores are formed in response to nutrient starvation. They can resist harsh environments and last for long periods of time. Once nutrients again become available, the endospore can germinate and the vegetative life cycle be resumed. LÄS MER

  4. 4. Protein disulfide isomerase : function and mechanism in oxidative protein folding

    Författare :Ruoyu Xiao; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Protein disulfide isomerase; endoplasmic reticulum; protein folding;

    Sammanfattning : The formation of native intramolecular disulfide bonds is critical for the folding and stability of many secreted proteins. This process involves oxidation of protein thiols to form disulfide bonds as well as rearrangement of any non-native disulfide bonds that might form. LÄS MER

  5. 5. Production and folding of proteins in the periplasm of Escherichia coli

    Författare :Rageia Elfageih; Jan-Willem de Gier; Hans-Georg Koch; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Escherichia coli; periplasm; recombinant protein production; disulfide bond containing proteins; translation initiation region; protein translocation machinery; co-translational folding; neuraminidases; biokemi; Biochemistry;

    Sammanfattning : The Gram-negative bacterium E. coli is the most widely used host for the production of recombinant proteins. Disulfide bond containing recombinant proteins are usually produced in the periplasm of E. coli since in this compartment of the cell - in contrast to the cytoplasm - disulfide bond formation is promoted.
