A two-dimensional spin-diffusion NMR study on the local structure of a water-soluble model peptide for Nephila clavipes dragline silk (MaSp1) before and after spinning
INTRODUCTION The dragline silk of the golden orb web spider Nephila clavipes has received significant attention because of its remarkable mechanical properties, which include toughness and high tensile strength.1,2 This silk contains two structural proteins designated as major ampullate spidroin 1 (MaSp1) and major ampullate spidroin 2 (MaSp2).3,4 The dominant MaSp1 can be described as AB block...
متن کاملSelf-assembly in the major ampullate gland of Nephila clavipes
We present a tentative interpretation of the origin of nematic liquid crystalline order exhibited by dragline silk fibroin solutions collected from the spider Nephila clavipes. Liquid crystallinity is thought to confer certain rheological properties on the fibroin solution which are exploited during the dragline spinning process. We show that the feasibility of liquid crystallinity under physio...
متن کاملComposition and Hierarchical Organisation of a Spider Silk
Albeit silks are fairly well understood on a molecular level, their hierarchical organisation and the full complexity of constituents in the spun fibre remain poorly defined. Here we link morphological defined structural elements in dragline silk of Nephila clavipes to their biochemical composition and physicochemical properties. Five layers of different make-ups could be distinguished. Of thes...
متن کاملMechanical properties of silk of the Australian golden orb weavers Nephila pilipes and Nephila plumipes
Silks from orb-weaving spiders are exceptionally tough, producing a model polymer for biomimetic fibre development. The mechanical properties of naturally spun silk threads from two species of Australian orb-weavers, Nephila pilipes and Nephilaplumipes, were examined here in relation to overall thread diameter, the size and number of fibres within threads, and spider size. N. pilipes, the large...
متن کاملAFM study of morphology and mechanical properties of a chimeric spider silk and bone sialoprotein protein for bone regeneration.
Atomic force microscopy (AFM) was used to assess a new chimeric protein consisting of a fusion protein of the consensus repeat for Nephila clavipes spider dragline protein and bone sialoprotein (6mer+BSP). The elastic modulus of this protein in film form was assessed through force curves, and film surface roughness was also determined. The results showed a significant difference among the elast...
