The PreQ1-I riboswitch is a cis-acting element identified in bacteria which regulates expression of genes involved in biosynthesis of the nucleoside queuosine (Q) from GTP. [1] PreQ 1 (pre-queuosine 1) is an intermediate in the queuosine pathway, and preQ 1 riboswitch, as a type of riboswitch, is an RNA element that binds preQ 1.
