Silk Spinning in Silkworms and Spiders
Spiders and silkworms spin silks that outcompete the toughness of all natural and manmade fibers. Herein, we compare and contrast the spinning of silk in silkworms and spiders, with the aim of identifying features that are important for fiber formation. Although spiders and silkworms are very distantly related, some features of spinning silk seem to be universal. Both spiders and silkworms prod...
متن کاملHow Spiders Spin Silk
Spider silk is wonderful stuff—light as the breeze and stretchy yet stronger than steel. People can manufacture synthetic fibers, such as Kevlar, that come close but can’t begin to match the process spiders use. Their silk proteins, called spidroins, rapidly convert from the soluble form to solid fibers at ambient temperatures and with water as the solvent. Not only is this beyond us, we don’t ...
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 کاملGround spiders overwhelm victims with supersticky silk.
Most spiders are content to sit and wait for unsuspecting victims to blunder into their silken traps, but webs are only ever as good as the structures that secure them to the surfaces that support them. ‘This [attachment] is done with a special type of silk, called piriform’, says Jonas Wolff, from Macquarie University, Australia, adding that most spiders only produce this silk when they need t...
متن کاملSpiders spinning electrically charged nano-fibres.
Most spider threads are on the micrometre and sub-micrometre scale. Yet, there are some spiders that spin true nano-scale fibres such as the cribellate orb spider, Uloborus plumipes. Here, we analyse the highly specialized capture silk-spinning system of this spider and compare it with the silk extrusion systems of the more standard spider dragline threads. The cribellar silk extrusion system c...
