A material produced by most spiders which has higher tensile strength than steel, and is equal to that of commercial polyaramid filaments—e.g., Twaron or Kevlar. It is extremely lightweight and ductile, can stretch up to 140% of its length without breaking and holds its strength to -40ºC Composition Complex proteins rich in alternating glycine and alanine, or alanine alone, that self-assemble into a beta sheet conformation
Because territorialism and cannibalism among spiders precludes spider farming as a viable means of manufacturing spider silk, researchers then genetically engineered other organisms--ranging from bacteria to goats--to produce those proteins, but spinning those proteins into useful fibers has proven expensive and slow.
The USTAR Bioproducts Scale-Up Facility at USU will enable scientists to produce synthetic spider silk and other synthetic bioproducts in quantities that will be useful for the production of real-world products.
The authors proposed a new 'lock and trigger' model for spider silk formation, in which gradual pairing up of the N-terminal domains locks spidroins into a network of many protein molecules, while the changes of structure in the C-terminal domains could trigger the rapid polymerization of spidroins into fibers.
