Engineering the Salmonella type III secretion system to export spider silk monomers.

13 Sep 2009 The type III secretion system (T3SS) exports proteins from the cytoplasm, through both the inner and outer membranes, to the external environment. Here, a system is constructed to harness the T3SS encoded within Salmonella Pathogeneity Island 1 to ... Read more...

Solution structure of eggcase silk protein and its implications for silk fiber formation.

18 May 2009 Spider silks are renowned for their excellent mechanical properties and biomimetic and industrial potentials. They are formed from the natural refolding of water-soluble fibroins with alpha-helical and random coil structures in silk glands into ... Read more...

Conservation of silk genes in Trichoptera and Lepidoptera.

14 May 2009 Larvae of the sister orders Trichoptera and Lepidoptera are characterized by silk secretion from a pair of labial glands. In both orders the silk filament consists of heavy (H)- and light (L)-chain fibroins and in Lepidoptera it also includes a P25 ... Read more...
