This research aims to clarify how transcription, translation, and mRNA degradation are coupled and regulated in bacteria.
Used genetic and kinetic analyses in Escherichia coli
Investigated spatial factors affecting coupling and degradation
Conducted comparative analyses with Bacillus subtilis and Caulobacter crescentus
High translational activity is required for transcription–translation coupling
Around half of the transcriptome shows signs of partial uncoupling
RNase E's membrane localization limits co-transcriptional mRNA degradation, affecting the coordination of gene expression
