XTEN‐based coiled‐coil telechelic protein hydrogels. a) XTEN flanked with physically associating coil domains exhibit shear‐thinning upon application of stress and self‐healing in its absence. b) Coiled‐coils form homopentameric bundles whose stability can be influenced through point mutations in the coil's primary sequence. c) Macroscopic gels are formed from each mutant construct. d) Gels reform rapidly following injection through a high‐gauge syringe needle, here shown for PXP. Scale bars = 500 µm.
