Abstract

(Figure presented.) A subset of E. coli transcripts localizes to the cell poles via an unknown mechanism. Here, the interaction of MinD and RNase E is shown to prevent site-specific degradation of polar mRNAs, thus favoring their enrichment in the cell poles. Candidate approach and proteomic analysis identify MinD and RNase E as regulators of polar mRNA localization. MinD interacts with a short peptide within the membrane-targeting sequence of RNase E. In the absence of MinD, RNase E transiently accumulates at cell poles. Polar accumulation of RNase E in ΔminCDE cells destabilizes polar mRNAs, resulting in their elimination from the poles and potentially affecting localization of the encoded proteins.
