Artificial spider silk proteins may form fibers with exceptional strength and elasticity. Wrapping silk, or aciniform silk, is the toughest of the spider silks, and has a very different protein composition than other spider silks. Here, we present the characterization of an aciniform protein (AcSp1) subunit named W 1 , consisting of one AcSp1 199 residue repeat unit from Argiope trifasciata . The structural integrity of recombinant W 1 is demonstrated in a variety of buffer conditions and time points. Furthermore, we show that W 1 has a high thermal stability with reversible denaturation at ∼71 °C and forms self‐assembled nanoparticle in near‐physiological conditions. W 1 therefore represents a highly stable and structurally robust module for protein‐based nanoparticle formation.
