  1. 6. Biomimetic spider silk and bioactive hydrogels formed by engineered recombinant spider silk proteins

    Författare :Tina Arndt; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Spider silk is a unique material and its properties have fascinated material scientists, biologists and physicians for decades. Spider silk display one of the highest toughness found among fibers in nature, is used by spiders for web-spinning, prey-wrapping and cocoon building, while scientists have explored its biomaterials properties for multiple purposes.

    Sammanfattning : In the recent past, spider silk has drawn significant attention from researchers mainly due to its distinguished mechanical strength, elasticity, biocompatibility and biodegradability. Technological advancements in genetic engineering have resulted in methods for creation of partial spider silk proteins. LÄS MER

  5. 9. Mechanisms of native and artificial spinning of spider silk

    Författare :Marlene Andersson; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Spider silk is tougher than all other known natural and man-made fibers, and represents an environmentally friendly material that could potentially be used for many different purposes, ranging from biomaterials to construction materials. However, for large-scale production of silk, methods to produce artificial silk fibers must be developed. LÄS MER

  7. 10. Of spiders, bugs, and men : Structural and functional studies of proteins involved in assembly

    Författare :Wangshu Jiang; Stefan D Knight; Steve J. Matthews; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Protein assembly; sulfate transporter; crystallography; Proteus mirabilis; fimbriae; adhesin; urinary tract infection; biofilm; spider silk; asymmetric dimer; Bri2; BRICHOS; molecular chaperone; Alzheimer s disease; amyloid; Biology with specialization in Structural Biology; Biologi med inriktning mot strukturbiologi;

    Sammanfattning : Protein assembly enables complex machineries while being economical with genetic information. However, protein assembly also constitutes a potential threat to the host, and needs to be carefully regulated.Sulfate is a common source of sulfur for cysteine synthesis in bacteria. LÄS MER
