approach for protein to be completely reversible to .

Abstract. Reversibility of protein denaturation is a prerequisite for all applications that depend on reliable enzyme catalysis, particularly, for using steam to sterilize enzyme reactors or enzyme sensor tips, and for developing protein-based devices that perform on–off switching of the protein function such as enzymatic activity, ligand binding and so on.

Amylin - Wikipedia

Amylin - Wikipedia

Amylin, or islet amyloid polypeptide (IAPP), is a 37-residue peptide hormone. It is cosecreted with insulin from the pancreatic β-cells in the ratio of approximately 100:1 (insulin:amylin). Amylin plays a role in glycemic regulation by slowing gastric emptying and promoting satiety, thereby preventing post-prandial spikes in blood glucose levels.. IAPP is processed from an 89-residue coding .
