Riboswitch - Preferred

Concept UI	M0545461
Scope note	Part of a MESSENGER RNA molecule that undergoes a conformation change upon binding a specific metabolite or other small molecule thereby regulating the messenger RNA's transcription, post-transcriptional processing, transport, translation, or stability in response to varying levels of the metabolite or other small molecule.
Preferred term	Riboswitch
Entry term(s)	Riboswitches

Ribosensors - Narrower

Concept UI	M0545462
Scope note	The metabolite/small molecule sensing domain of riboswitches.
Preferred term	Ribosensors
Entry term(s)	Ribosensor
