Metamorphic protein
# Metamorphic protein

A metamorphic protein is a protein that can adopt two or more shapes (also known as folds) each having a different function.

The fold of a protein is defined by how the two-dimensional linear protein polypeptide folds up into a three-dimensional structure. Most proteins adopt a single stable fold. But some proteins have marginal structural stability and can rapidly interconvert between two or more folds. It has been estimated that up to four percent of proteins maybe have this fold chaining property.
