Albeit silks are fairly well understood on a molecular level, their hierarchical organisation and the full complexity of constituents in the spun fibre remain poorly defined. Here we link… Expand
Characterization of the protein components of Nephila clavipes dragline silk.

- Medicine, Chemistry
- 2 March 2005
Spider silk is predominantly composed of structural proteins called spider fibroins or spidroins. The major ampullate silk that forms the dragline and the cobweb's frame threads of Nephila clavipes… Expand
Proline and processing of spider silks.
Major ampullate (MAA) silks from a variety of spider species were collected by artificial silking that adjusted the samples to have similar breaking strains. Those silks are highly comparable in… Expand
Differential polymerization of the two main protein components of dragline silk during fibre spinning

Spider silks are some of the strongest materials found in nature1,2. Achieving the high tensile strength and elasticity of the dragline of orb-weaving spiders, such as Nephila clavipes3,4,5, is a… Expand
The conserved C-termini contribute to the properties of spider silk fibroins.

- 16 December 2005
Spider silk fibroins can adopt different structural states at high protein concentrations. They are soluble within the spinning dope of the glands, but readily converted into insoluble polymers upon… Expand
Conserved C-termini of Spidroins are secreted by the major ampullate glands and retained in the silk thread.
The C-termini of Spidroins produced in the major and minor ampullate glands of spiders are highly conserved. Despite this conservation, no corresponding peptides have been identified in the spinning… Expand
Containment of Extended Length Polymorphisms in Silk Proteins
- A. Chinali, W. Vater, +5 authors K. Weißhart
- Biology, Medicine
- Journal of Molecular Evolution
- 27 March 2010
The spider silk gene family to the current date has been developed by gene duplication and homogenization events as well as conservation of crucial sequence parts. These evolutionary processes have… Expand
Spider silk as a resource for future biotechnologies
- A. Sponner
- 1 December 2007
Insect silks have been used by mankind for millennia to produce textiles and in particular, the cocoon silk of Bombyx mori was the base of one of the most important industries in history. In fact, B.… Expand
Bottle-necks for nutrient acquisition of maize at low root temperatures
Maize plants were grown in nutrient solution at 12°C root-zone temperature (RZT) with their shoot base, including the apical shoot meristem, either at high or low temperature (high SBT or low SBT).… Expand
