(a) Rheological dynamic time sweeps of PP1 monitoring the storage modulus (G’) as a function of time, peptide, and enzyme concentration. (b) Shear thin-recovery of 1.0 wt% dephosphorylated PP1 hydrogel. Time sweep (6.0 rad/s and 0.2 % strain) for 1.0 h shows initial formation of gel, followed by an applied 1000% strain for 30 s to thin the gel, with a final time sweep (6.0 rad/s and 0.2 % strain) for 1.0 h to show rapid recovery of hydrogel stiffness.
