Structural gymnastics of multifunctional metamorphic proteins.

ABSTRACT: The classic structure-function paradigm holds that a protein exhibits a single well-defined native state that gives rise to its biological function. Nonetheless, over the past few decades, numerous examples of proteins exhibiting biological function arising from multiple structural states of varying disorder have been identified. Most recently, several examples of 'metamorphic proteins', able to interconvert between vastly different native-like topologies under physiological conditions, have been characterised with multiple functions. In this review, we look at the concept of protein metamorphosis in relation to the current understanding of the protein structure-function landscape. Although structural dynamism observed for metamorphic proteins provides a novel source of functional versatil
