(a) Comparison of PEVK's persistence length with predictions of the OSF theory of polyelectrolyte chains. (b) Glutamate-glutamate (E-E) and lysine-lysine (K-K) average neighbor distance along the PEVK segment. (c) PEVK segment extensibility and passive force as a function of SL. Fractional extension of the PEVK segments was calculated based on the experimentally derived persistence lengths at 167 mM ionic strength.
