Code for Atlas of mRNA translation and decay for bacteria

Regulation of mRNA stability is a central process in gene expression. Here, report an atlas of 5´ monophosphorylated mRNA decay intermediates (5´P) in 96 species. We use those data to demonstrate that in species with 5´-3´exonuclease activity, the exoribonuclease RNase J follows the trailing ribosome, producing an in vivo single-nucleotide toeprint of its 5´ position. While in other species, ribosome position alters endonucleolytic cleavage sites. Our work demonstrates the universal connection between RNA decay and translation and paves the way for use of metadegradome sequencing to investigate post-transcriptional regulation of unculturable species present and complex microbial communities.

Here we release the code for that work.
