Title:
HIGH MOLECULAR WEIGHT RECOMBINANT SILK OR SILK-LIKE PROTEIN, AND MICRO- OR NANOSCALE SPIDER-WEB FIBER OR SPIDER-WEB-LIKE FIBER PRODUCED USING THE RECOMBINANT SILK OR SILK-LIKE PROTEIN
Document Type and Number:
WIPO Patent Application WO/2011/112046
Kind Code:
A2
Abstract:
The present invention relates to high molecular weight recombinant silk or silk-like protein, which has a molecular weight that is almost equivalent to that of natural silk protein, and to micro- or nanoscale spider-web fiber or spider-web-like fiber having improved physical properties produced using the recombinant silk of the silk-like protein. The recombinant silk or the silk-like protein according to the present invention is advantageous in that it has a high molecular weight like the dragline silk protein produced by a spider, and exhibits physical properties similar or superior to the natural silk protein when produced into fiber. Therefore, the recombinant silk or the silk-like protein, and the spider-web fiber or spider-web-like fiber produced using the recombinant silk or silk-like protein according to the present invention can be significantly valuably used in a variety of industrial fields, such as the biotechnological fields and/or medicinal fields to which spider-web fibers are applicable.
