Riboswitch RNAs whose abundance is dependent on RNase Y expression. [PDF]
, 2013 Transcriptional profiles of a selection of six riboswitches controlling the expression of the downstream gene via transcriptional attenuation are shown. In all cases the terminated leader transcript accumulates strongly when strain SSB447 (Pspac-rny) is ...

The structure of the SAM/SAH-binding riboswitch [PDF]
, 2018 S-adenosylmethionine (SAM) is a central metabolite since it is used as a methyl group donor in many different biochemical reactions. Many bacteria control intracellular SAM concentrations using riboswitch-based mechanisms.

The return of metabolism: biochemistry and physiology of glycolysis
Biological Reviews, Volume 101, Issue 2, Page 751-803, April 2026.ABSTRACT Glycolysis is a fundamental metabolic pathway central to the bioenergetics and physiology of virtually all living organisms. In this comprehensive review, we explore the intricate biochemical principles and evolutionary origins of glycolytic pathways, from the classical Embden–Meyerhof–Parnas (EMP) pathway in humans to various prokaryotic and ...

Postepy biochemii, 2005 Riboswitches are RNA structures able to bind small molecules and regulate gene expression at both, transcriptional and translational level. They are present in a wide variety of bacterial species. In Bacillus subtilis more than 2% of the genome is regulated by riboswitches. Metabolite binding is highly specific and can be provided in cooperative manner.

Structural Basis for Molecular Discrimination by a 3′,3′-cGAMP Sensing Riboswitch
Cell Reports, 2015 Cyclic dinucleotides are second messengers that target the adaptor STING and stimulate the innate immune response in mammals. Besides protein receptors, there are bacterial riboswitches that selectively recognize cyclic dinucleotides.
