Finally, such protein engineered triblock copolymers capable of forming robust hydrogels hold tremendous promise for biomedical applications in drug delivery and tissue engineering. While both CEC and C L44AEC L44A assemble into micelles, CEC is more densely packed with C domains on the surface enabling the development of networks leading to hydrogel formation. The negative control C L44AEC L44A does not exhibit binding to small molecule and is inelastic at lower temperatures, affirming the favorable role of C domain and its helical conformation. The CEC triblock polymer demonstrates increased small molecule binding and ideal elastic behavior for hydrogel formation. To understand how the two C domains improve small molecule recognition and the mechanical integrity of CEC, we have constructed C L44AEC L44A, which bears an impaired C L44A domain that is unstructured as a negative control. In this paper, recombinant methods have been used to engineer artificial protein triblock polymers composed of two different self-assembling domains (SADs) bearing one elastin (E) flanked by two cartilage oligomeric matrix protein coiled-coil (C) domains to generate CEC.
