- Abstract
- Elastin-like polypeptides (ELPs) are stimulus-responsive protein-based biopolymers that exhibit phase transition behavior. By joining them to synthetic phytochelatin (EC), EC-ELP fusion proteins with temperature sensitivity and metal-binding functionality were generated to remove heavy metal ions biologically. Three different EC domains (EC10, EC20, EC30) were incorporated into the ELP, and the EC-ELP fusion proteins were expressed in E. coll. Their thermal properties and metal binding abilities were then investigated according to the EC length. In addition, the feasibility of reusing EC-ELPs and the cadmium ion binding affinity of reused EC-ELPs were explored.
