International Classification:
C12N 1500 C12N 120 C07H 2104
US Classification:
4351721
Abstract:
A hybrid vector produced from a linearized cosmid and arms from. lambda. phage vector DNA has been developed. The hybrid vector can be used to generate fragments which are useful as vectors in a helper phage-mediated transformation system, permitting large fragments of foreign DNA to be introduced into a host on an industrial scale.

US Classification:
435 691
Abstract:
Cloned DNA encoding spider flagelliform silk proteins described. The translated amino acid sequence of the cloned cDNA shows that the flagelliform silk protein is composed largely of repeated motifs. The dominant motif of this protein is Gly-Pro-Gly-Gly-X, which can appear up to 63 times in tandem arrays. This motif likely forms Pro. sup. 2 -Gly. sup. 3 type II. beta. -turns. The resulting series of concatenated. beta. -turns are thought to form a helix (. beta. -spiral). The present inventors propose that this spring-like. beta. -spiral is the basis of the elasticity of silk.

C12N 121 C07H 2104 C07K 14435
US Classification:
4352523
Abstract:
cDNA clones encoding minor ampullate spidroin proteins (MiSP) are described. The translated amino acid sequence of the cloned cDNA shows that the MiSPs have a structure which exhibits an amino proximal nonrepetitive region, a repetitive portion and a carboxy-proximal nonrepetitive portion. The repetitive portion of the sequence is describable by a generic repeat formula. Comparison of the amino acid sequences derived from the translation with the sequences of short peptides obtained from solubilized minor ampullate spider silk suggests that the nonrepetitive portions of the protein are cleaved from the protein during secretion from the cells synthesizing the spidroins. This comparison also suggests that the minor ampullate spider silk is composed of at least three polypeptides.

worm silk alone. The best fiber they created is about 48 percent stronger than regular silk and has about 61 percent the overall strength of dragline spider silk, which is the strongest silk that spiders make, said Randolph Lewis, a biologist at Utah State University who worked on the new composite.
