Biochem/physiol Actions

PreQ1 (pre-queuosine1) is an intermediate of the queuosine pathway. Also, PreQ1 binds with high affinity to the aptamer of PreQ1 riboswitch, which attenuates protein expression.
PreQ1 (pre-queuosine1), an intermediate of the queuosine pathway, regulates the PreQ1 riboswitch.
PreQ1 is a nucleobase derived from guanine[1] and a precursor of the modified base queuosine that is present in four tRNAs.[2] Prequeuosine (preQ1) riboswitches are RNA regulatory elements present in the 5′ UTR of genes that participates in the biosynthesis and transport of preQ1.[2]

Single-stranded noncoding regulatory RNAs, as exemplified by bacterial riboswitches, are highly dynamic. The conformational dynamics allow the riboswitch to reach maximum switching efficiency under appropriate conditions. Here we characterize the conformational dynamics of preQ1 riboswitches from mesophilic and thermophilic bacterial
