Elastomechanical properties of resilin

We report the results of the first investigation on the effect of polarity on the elastic properties of an elastomeric protein resilin found in different insects. We simulate tensile tests on four naturally occurring resilin motifs. We repeat simulations on reduced-polarity counterparts of these motifs by setting the charge on each atom to zero, setting the charge on each atom to one-half of the natural value, as well as by replacing all of the …
