Recombinant DNA production of spider silk proteins
Spider dragline silk is considered to be the toughest biopolymer on Earth due to an extraordinary combination of strength and elasticity. Moreover, silks are biocompatible and biodegradable protein-based materials. Recent advances in genetic engineering make it possible to produce recombinant silks in heterologous hosts, opening up opportunities for large-scale production of recombinant silks f...
متن کاملToward spinning artificial spider silk.
Spider silk is strong and extensible but still biodegradable and well tolerated when implanted, making it the ultimate biomaterial. Shortcomings that arise in replicating spider silk are due to the use of recombinant spider silk proteins (spidroins) that lack native domains, the use of denaturing conditions under purification and spinning and the fact that the understanding of how spiders contr...
متن کاملInterfacial rheological properties of recombinant spider-silk proteins.
Freestanding protein films are interesting for many applications ranging from microencapsulation to tissue engineering. Here, the authors use interfacial rheology to characterize the adsorption kinetics and the rheology of spider-silk films formed at an oil water interface. The high surface activity of the engineered spider-silk proteins results in a fast formation of highly stable films, which...
متن کاملNovel Assembly Properties of Recombinant Spider Dragline Silk Proteins
Spider dragline silk, which exhibits extraordinary strength and toughness, is primarily composed of two related proteins that largely consist of repetitive sequences. In most spiders, the repetitive region of one of these proteins is rich in prolines, which are not present in the repetitive region of the other. The absence of prolines in one component was previously speculated to be essential f...
متن کاملIdentification of Wet-Spinning and Post-Spin Stretching Methods Amenable to Recombinant Spider Aciniform Silk.
Spider silks are outstanding biomaterials with mechanical properties that outperform synthetic materials. Of the six fibrillar spider silks, aciniform (or wrapping) silk is the toughest through a unique combination of strength and extensibility. In this study, a wet-spinning method for recombinant Argiope trifasciata aciniform spidroin (AcSp1) is introduced. Recombinant AcSp1 comprising three 2...
