protein conformational switch
Also known as: molecular switch
Taxonomy: Mechanism Branch / Architecture. Workflows sit above the mechanism and technique branches rather than replacing them.
Summary
A protein conformational switch is an engineered protein system in which a signaling event induces a conformational change. Reported uses include reagent-free biosensing and regulation of biological function.
Usefulness & Problems
Why this is useful
This tool class is useful because it converts signaling events directly into protein structural changes, enabling reagent-free biosensors and proteins with regulated activity. The cited literature frames these switches as a way to endow proteins that previously lacked switching behavior with controllable responses.

Problem solved
It addresses the problem of creating proteins that respond to signaling inputs with a functional structural transition. This supports biosensing and functional regulation without requiring added reagents, according to the cited review.
