Webb10 apr. 2024 · Riboswitch diversity and distribution. Riboswitches are commonly used by bacteria to detect a variety of metabolites and ions to regulate gene expression. To date, nearly 40 different classes of riboswitches have been discovered, experimentally validated, and modeled at atomic resolution in complex with their cognate ligands. Webb1 juni 2024 · These RNA switches require only little coding space and operate without any additionally expressed proteins, making them ideal tools for gene regulation in size-limited systems. As of today, riboswitches can be used to intervene with gene expression at almost every step in the life-cycle of a messenger RNA (mRNA). ships paint
