The ftsZ-DE RNA motif is a conserved RNA structure that was discovered by bioinformatics.ftsZ-DE motifs are found in bacteria belonging to the genus Fibrobacter. It is ambiguous whether ftsZ-DE RNAs function as cis-regulatory elements or whether they operate in trans as small RNAs.ftsZ-DE RNAs are consistently located immediately downstream of predicted operons, one of whose genes is predicted as ftsZ. ftsZ genes encode a GTPasethat is involved in cell division.This genomic arrangement could suggest that ftsZ-DE RNAs function as cis-regulatory elements as part of the 3' untranslated regions of these operons. However, these locations rarely contain cis-regulatory RNAs in bacteria. Another possibility that was proposed is that ftsZ-DE RNAs represent an unusual form of Rho-independent transcr
