Abstract in another language

Rigid threads: Lacewings protect their eggs from predators by laying them on small stalks (see picture). The stalks have good mechanical properties and, unlike most other silks, a cross β structure. An artificial egg stalk was produced using a designed recombinant variant of a sequenced lacewing egg stalk protein, and it attained 90 % of the tensile strength of a natural egg stalk.

Abstract in another language

Ei am Stiel: Florfliegen schützen ihre Eier vor Fraßfeinden auf kleinen Stielen (siehe Bild). Die Stiele haben gute mechanische Eigenschaften und anders als die meisten Seiden eine Cross-β-Struktur. Aus einem artifiziellen und rekombinant hergestellten Protein nach dem Vorbild eines sequenzierten Florfliegen-Eierstielproteins konnte ein künstlicher Stiel produziert werden, der 90 % der Zugfestigkeit eines natürlichen Stiels aufweist.
