Fouru rna thermometer
WebSep 18, 2014 · RNA thermometers trap the ribosome binding site (RBS) and/or the translation initiation codon (AUG) of an mRNA by base pairing within a secondary structure. An increase in temperature to 37°C (virulence genes) or 40–42°C (heat shock genes) destabilizes the structure in a reversible, zipper-like manner. WebRNA thermometers are translational control elements that regulate the expression of bacterial heat shock and virulence genes. They fold into complex secondary structures …

WebNov 27, 2024 · A large number of bacteria have been found to govern virulence and heat shock responses using temperature-sensing RNAs known as RNA thermometers. A prime example is the agsA thermometer known to regulate the production of the AgsA heat shock protein in Salmonella enterica using a “fourU” structural motif. WebFourU thermometers are a class of non-coding RNA thermometers found in Salmonella.[1] They are named 'FourU' due to the four highly conserved uridine nucleotides found directly opposite the Shine-Dalgarno sequence on hairpin II . RNA thermometers such as FourU control regulation of temperature via heat shock proteins in many …
WebFeb 22, 2024 · A brief description of two types of bacterial RNATs illustrates the important functions of these thermosensing mechanisms. One is the FourU thermosensor of the pathogen Salmonella typhimurium ( Rinnenthal et al., 2011 ). This RNAT is termed a FourU thermometer because four consecutive uridines form base pairs with part of the S–D …
