Spider capture silk is a natural material that outperforms almost any synthetic material in its combination of strength and elasticity. The structure of this remarkable material is still largely unknown, because spider-silk proteins have not been crystallized. Capture silk is the sticky spiral in the webs of orb-weaving spiders. Here we are investigating specifically the capture spiral threads from Araneus, an ecribellate orb-weaving spider. The major protein of these threads is flagelliform… 
Nanostructure and molecular mechanics of spider dragline silk protein assemblies
TLDR
At atomic-level structures of MaSp1 and MaSp2 proteins from the Nephila clavipes spider dragline silk sequence are obtained using replica exchange molecular dynamics, and subject these structures to mechanical loading for a detailed nanomechanical analysis.
The elaborate structure of spider silk
TLDR
This article focuses on the structure‑function relationship of the characterized highly repetitive spider silk spidroins and their conformational conversion from solution into fibers and is of crucial importance to understanding the intrinsic properties of spider silk.
Atomic Force Microscopy and Spectroscopy of Silk from Spider Draglines, Capture-Web Spirals, and Silkworms
Atomic force microscopy (AFM) of silk proteins usually shows segmented nanofibers, or fields of globules, or both. The sizes of the globules are similar to the sizes of the segments in the
Uncovering the structure-function relationship in spider silk
All spiders produce protein-based biopolymer fibres that we call silk. The most studied of these silks is spider dragline silk, which is very tough and relatively abundant compared with other types
Molecular mechanics of silk nanostructures under varied mechanical loading
TLDR
The authors have explored the effects of the poly‐alanine length of the N. clavipes MaSp1 peptide sequence and identify differences in nanomechanical loading conditions on the behavior of a unit cell of 15 strands with 840–990 total residues to represent a cross‐linking β‐sheet crystal node in the network within a fibril of the dragline silk thread.
Modifications of spider silk sequences in an attempt to control the mechanical properties of the synthetic fibers
TLDR
The data presented suggest that increasing temperatures seem to be positively correlated with β-sheet formation for both proteins and this state is irreversible or reversible when both X (5th and 10th) in the elastic motif are hydrophilic or hydrophobic respectively.
The role of elastomeric network chains in the mechanics of spider silks
Orb-weaving spiders produce capture-webs from two mechanically distinct silk types, major ampullate silk (MA) and flagelliform silk (FL), constructed from proteins with a block-copolymer structure
Spider Silk‐Inspired Artificial Fibers
TLDR
In this review, the authors summarize the study of the structure and properties of natural spider silk, and the biomimetic preparation of artificial fibers from different types of molecules and polymers by taking some examples of artificial fiber exhibiting these interesting properties.
Spider capture silk: performance implications of variation in an exceptional biomaterial.
TLDR
A large comparative data set is presented that allows examination of capture silk properties across orb-weaving spider species, finding that material properties vary greatly across species and some material and mechanical properties are evolutionarily correlated.
Atomistic model of the spider silk nanostructure
Spider silk is an ultrastrong and extensible self-assembling biopolymer that outperforms the mechanical characteristics of many synthetic materials including steel. Here we report atomic-level

Segmented nanofibers of spider dragline silk: Atomic force microscopy and single-molecule force spectroscopy
TLDR
Force spectra for single molecules of the silk protein demonstrate that this protein unfolds through a number of rupture events, indicating a modular substructure within single silk protein molecules.
The mechanical design of spider silks: from fibroin sequence to mechanical function.
TLDR
Comparison of MA silks from Araneus diadematus and Nephila clavipes shows variation in fibroin sequence and properties between spider species provides the opportunity to investigate the design of these remarkable biomaterials.
Spider Silk Fibers Spun from Soluble Recombinant Silk Produced in Mammalian Cells
TLDR
The wet spinning of silk monofilaments spun from a concentrated aqueous solution of soluble rc–spider silk protein (ADF-3; 60 kilodaltons) under modest shear and coagulation conditions showed toughness and modulus values comparable to those of native dragline silks but with lower tenacity.
Evidence from flagelliform silk cDNA for the structural basis of elasticity and modular nature of spider silks.
TLDR
It is shown that all spider silk proteins can be characterized as sets of shared structural modules, which suggests that unusual homogenization processes are involved in silk protein evolution.
Liquid crystalline spinning of spider silk
TLDR
Successful copying of the spider's internal processing and precise control over protein folding, combined with knowledge of the gene sequences of its spinning dopes, could permit industrial production of silk-based fibres with unique properties under benign conditions.
