Novel 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 کاملSpider Dragline Silk Molecular Properties and Recombinant Expression
Rising, A. 2007. Spider dragline silk – molecular properties and recombinant production. Doctor’s dissertation. ISSN: 1652-6880, ISBN: 978-91-576-7337-4 Spider dragline silk possesses several desirable features of a biomaterial; it has extraordinary mechanical properties, is biocompatible and biodegradable. It consists of large proteins, major ampullate spidroins (MaSp:s), that contain alternat...
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 کاملRecombinant 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 کاملNanostructure and molecular mechanics of spider dragline silk protein assemblies.
Spider silk is a self-assembling biopolymer that outperforms most known materials in terms of its mechanical performance, despite its underlying weak chemical bonding based on H-bonds. While experimental studies have shown that the molecular structure of silk proteins has a direct influence on the stiffness, toughness and failure strength of silk, no molecular-level analysis of the nanostructur...
