COMPOSITIONS AND METHODS FOR FABRICATING SYNTHETIC DRAGLINE SPIDER SILK

摘要

Compositions comprising a mixture of proteins derived from MaSP, nucleic acids encoding same and method for the preparation of synthetic dragline spider silk are provided. The compositions of the invention comprise a mixture of proteins of differing molecular weight, wherein each protein of said mixture comprises, independently, multiple repeats of a repetitive region of a MaSP (major ampullate spidroin) protein or a functional homolog, variant, derivative or fragment thereof.
