Short summary
While most proteins adopt one conformation, several interconvert between two or more very different structures. Knowing how sequence changes and small-molecule binding can control this behavior is essential for both understanding biology and inspiring new “molecular switches” which can control cellular pathways. This work contributes by examining these topics in the ARNT protein, showing that features of both the folded and unfolded states contribute to the interconversion process.
