Variation of mechanical properties with amino acid content in the silk of Nephila clavipes.


In this paper, we explore the impact of dietary deprivation, where spiders are provided diets missing one or more of the amino acids, on the properties of the spider dragline silk spun after one month on the diet. Cohorts of female N. clavipes spiders were selected for diets deprived of alanine (Ala) and glycine (Gly), arginine (Arg), leucine (Leu), or… (More)
