Thiamine riboswitch
Web19 Jan 2024 · For instance, the AdoCbl riboswitch cannot bind to methylcobalamin or cyanocobalamin (Nahvi, 2004), and the TPP-binding riboswitch does not interact with thiamine or thiamine monophosphate (TMP) (Lang et al., 2007). This specificity is due to the evolutionary conservation of sequence and structural features. Web7 Apr 2024 · This approach allowed the authors to select functionally competent riboswitch variants based on their ability to regulate the mNeon gene in the absence or presence of exogenously added cyanocobalamin (CNCbl) effector. ...

In bacteria, many genes involved in the biosynthesis of cofactors such as thiamine pyrophosphate (TPP) are regulated by ribo switches, regions in the 5′ …
Web30 Oct 2024 · Thiamine pyrophosphate (TPP)-sensing riboswitches are the most widespread riboswitch class known in bacteria. They have also been identified in fungi [ 16], archaea, and plants [ 16 - 18], and are among the earliest discovered riboswitch representatives. Web3 Mar 2014 · RNA is usually classified as either structured or unstructured; however, neither category is adequate in describing the diversity of secondary structures expected in biological systems We describe this diversity within the ensemble of structures by using two different metrics: the average Shannon entropy and the ensemble defect. The average …
Web9 May 2008 · The thiamine pyrophosphate (TPP)-sensing riboswitch is the only riboswitch found in eukaryotes. In plants, TPP regulates its own production by binding to the 3' untranslated region of the mRNA encoding ThiC, a critical enzyme in thiamine biosynthesis, which promotes the formation of an unstable splicing variant ...
