Evidence of Decoupling Protein Structure from Spidroin Expression in Spider Dragline Silks
The exceptional strength and extensibility of spider dragline silk have been thought to be facilitated by two spidroins, major ampullate spidroin 1 (MaSp1) and major ampullate spidroin 2 (MaSp2), under the assumption that protein secondary structures are coupled with the expressed spidroins. We tested this assumption for the dragline silk of three co-existing Australian spiders, Argiope keyserl...
متن کاملStructural hysteresis in dragline spider silks induced by supercontraction: An x-ray fiber micro-diffraction study.
Interaction with water causes shrinkage and significant changes in the structure of spider dragline silks, which has been referred to as supercontraction in the literature. Preferred orientation or alignment of protein chains with respect to the fiber axis is extensively changed during this supercontraction process. Synchrotron x-ray micro-fiber diffraction experiments have been performed on Ne...
متن کاملElasticity of Spider Dragline Silks Viewed as Nematics: Yielding Induced by Isotropic-Nematic Phase Transition
Spider dragline silk (SDS), the main structural web silk regarded as the “spider’s lifeline", exhibits a fascinating combination of high tensile strength and high extensibility (1). Its toughness is over 10 times that of Kevlar, the material for making bullet-proof suits (2). In addition, SDS has a unconventional sigmoidal shaped stress-strain curve and shape memory capability after the tension...
متن کاملPhysicochemical Position-Dependent Properties in the Protein Secondary Structures
Background: Establishing theories for designing arbitrary protein structures is complicated and depends on understanding the principles for protein folding, which is affected by applied features. Computer algorithms can reach high precision and stability in computationally designing enzymes and binders by applying informative features obtained from natural structures. Methods: In this study, a ...
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...
